We'll play board games at the [Land-Grant Brewing Company](https://landgrantbrewing.com/). They have multiple [food trucks](https://landgrantbrewing.com/food/) on Sundays. Ray Ray's also has coffee, and the brewery has free water (and Jeni's ice cream). You can come late or leave early. Please just sign up so I know to expect you. **Notes on Parking** * You'll (probably) have to park on the street, but street parking is free on Sundays. * There are [parking garages](https://landgrantbrewing.com/parking/) a little farther away if you want. These are obviously not free, though. * There is a [lot next door](https://www.google.com/maps/place/39%C2%B057'26.0%22N+83%C2%B000'40.9%22W/@39.957211,-83.0119921,19z/data=!3m1!4b1!4m12!1m7!3m6!1s0x88388f3efd89238b:0xc139207386232411!2sLand-Grant+Brewing+Company!8m2!3d39.9577613!4d-83.011426!16s%2Fg%2F1pzt7t9df!3m3!8m2!3d39.957211!4d-83.011347?entry=ttu&g_ep=EgoyMDI2MDEyMS4wIKXMDSoKLDEwMDc5MjA3MUgBUAM%3D) to the brewery that you're allowed to park in, but it is not free. I've never parked there, so I don't know anything about rates. (I'm told though that if you eat at Milo's Deli next door to this lot that Milo's will stamp your parking so it's free.) * You're going to see odd signs on [Lucas St](https://www.google.com/maps/place/39%C2%B057'26.1%22N+83%C2%B000'40.3%22W/@39.957256,-83.0124134,19z/data=!3m1!4b1!4m10!1m5!3m4!2zMznCsDU3JzI4LjgiTiA4M8KwMDAnNDEuNSJX!8m2!3d39.957993!4d-83.011536!3m3!8m2!3d39.957256!4d-83.011197?entry=ttu&g_ep=EgoyMDI2MDEyMS4wIKXMDSoKLDEwMDc5MjA3MUgBUAM%3D) (saying it's a "private street") that will lead you to believe you're not allowed to park there, but you actually are. * Columbus parking cops literally do not work on Sundays. This means that, even if you're driving a non-EV, you can park in the EV spots near the brewery. **Games** I do bring many games, but please bring some of your own as well.

***(She loves me!)* A Brief History of Quarry Trails** [Quarry Trails Metro Park](https://www.metroparks.net/parks-and-trails/quarry-trails/) traces its origins to a vast limestone quarry operated by the Marble Cliff Quarry Company starting in the early 20th century. The site, located along the Scioto River west of downtown, supplied crushed stone for local construction projects and roads throughout central Ohio. Operations peaked mid-century, with massive excavation creating deep pits and steep cliffs that reshaped the landscape. By the 1980s, demand declined, and the southern section of the quarry closed (with the northern section of the quarry remaining in operation to this day by a separate company), leaving behind scarred terrain and abandoned equipment. Environmental concerns arose as the area became a dumping ground and off-road playground for locals. Columbus Metro Parks began eyeing the property in the 1990s for potential reclamation into public green space. In 2015, Metro Parks acquired the initial 180 acres from the quarry's owners, marking a pivotal step toward transformation. Thrive Companies, a local developer, partnered in the deal to build adjacent housing while funding park improvements. Cleanup efforts removed tons of debris, stabilized cliffs, and addressed water quality in the flooded quarries. Planners envisioned a mix of adventure and preservation, incorporating the site's industrial remnants as features. Community input from nearby Grandview Heights and Hilliard residents shaped early designs. The project gained momentum with state and federal grants supporting habitat restoration. The park officially opened its first phase in November 2021, featuring 3.5 miles of trails, a waterfall overlook, and climbing walls on the quarry faces. Visitors quickly embraced the unique terrain, with mountain biking loops and a 25-foot waterfall drawing crowds from across the metro area. Metro Parks added a canoe/kayak launch on the Scioto River, connecting to the city's broader trail network. Dog parks and picnic areas rounded out the amenities, making it a year-round destination. Expansion continued with land acquisitions pushing the total toward 600 acres. By 2023, the park hosted events like guided hikes and birdwatching tours. Ongoing development includes a planned adventure center with zip lines and more extensive single-track trails set for completion in the coming years. Metro Parks collaborates with conservation groups to plant native species and monitor wildlife returning to the reclaimed quarries. The site now serves as an educational hub, with interpretive signs explaining its quarrying past and ecological recovery. Local schools incorporate field trips to study geology and restoration science. Quarry Trails exemplifies Columbus's shift from industrial reuse to innovative urban parks. It stands as the newest addition to the Metro Parks system, complementing favorites like Scioto Audubon and Highbanks. Today, Quarry Trails continues evolving, with future phases adding connections to the Olentangy Trail and more water access points. Annual visitor numbers have surged, boosting nearby businesses in the evolving west side neighborhoods. The park's success has inspired similar reclamation projects elsewhere in the region. It highlights how Columbus balances growth with green space preservation. Residents enjoy a one-of-a-kind spot that honors the area's gritty history while offering modern recreation. Quarry Trails remains a testament to community vision and adaptive reuse in our city. ***(She loves me not.)* A Briefer History of Valentine's Day** The origins of Valentine's Day trace back to ancient Rome and the festival of Lupercalia, celebrated in mid-February to honor fertility and purification rites. During this raucous event, young men drew names of women from a box in a matchmaking lottery, often leading to pairings or marriages. By the late 5th century, Pope Gelasius I officially replaced Lupercalia with St. Valentine's Day on February 14 to Christianize the pagan holiday. Although several early Christian martyrs were named Valentine, the most commonly associated figure is a 3rd-century Roman priest who secretly married couples against Emperor Claudius II's ban on young men marrying, believing single soldiers fought better. Legend claims Valentine was imprisoned and later executed on February 14, around 269–270 AD. The romantic associations with Valentine's Day emerged much later, during the Middle Ages. The pivotal moment came in the late 14th century when Geoffrey Chaucer, in his poem "Parlement of Foules" (c. 1381), linked St. Valentine's Day with courtship, writing that birds chose their mates on this date. This literary connection spread rapidly among the English and French nobility, transforming the saint's feast day into a celebration of romantic love. By the 15th century, lovers began exchanging handwritten notes called "valentines," often containing verses or simple declarations of affection. In the 18th and 19th centuries, Valentine's Day became increasingly commercialized, especially in England and later the United States. The introduction of printed valentines in the 1840s, pioneered by Esther Howland in America, turned personal notes into mass-produced cards adorned with lace, ribbons, and Cupid imagery. Factories began producing elaborate cards, and the tradition of giving flowers (especially roses), chocolates, and jewelry took hold during the Victorian era. Today, February 14 is one of the most widely celebrated secular holidays worldwide, generating billions in spending on cards, candy, flowers, and romantic dinners. While still officially the feast day of Saint Valentine in some Christian traditions, the modern version has largely shed its religious roots in favor of universal expressions of love and friendship. From ancient fertility rites to global commercial phenomenon, Valentine's Day has evolved dramatically over two millennia while retaining its core focus on human connection. ***(She loves me!)* Map of the Park** Here is a [Map of Quarry Trails](https://www.metroparks.net/wp-content/uploads/2025/09/Quarry-Trails_JUNE-2025_1980px-Web.jpg). ***(She loves me not.)* Summary** For this hike, we'll do a loop of the park. This will be about four miles. Now, this won't be one of our longer hikes. However, in my experience, Quarry Trails tends to wear people out more quickly than other parks. I suspect this is because most of the trails are either paved or heavily graveled (no surprise at a park which abuts an active stone quarry), with some elevation changes along the way. ***(She loves me!)* Where We'll Meet** Quarry Trails has multiple entrances, but none of them are connected internally within the park. So you must drive to the correct one for this event. Set your GPS to [2319 Quarry Trails Dr, Hilliard, OH 43026](https://www.google.com/maps/place/2319+Quarry+Trails+Dr,+Hilliard,+OH+43026/@39.9998462,-83.0873077,17z/data=!3m1!4b1!4m6!3m5!1s0x883891dd76f5eedf:0xf1cb9d34c1069580!8m2!3d39.9997868!4d-83.0872621!16s%2Fg%2F11y17k0ms5?entry=ttu&g_ep=EgoyMDI1MTExMi4wIKXMDSoASAFQAw%3D%3D), or use the map pin I've provided here. Do not just type "Quarry Trails" into Google Maps and expect it to take you to the correct place. It probably won't. We will meet in the parking lot of the Lake Area. The best entrance to this parking lot will be your first left off of Quarry Trails Dr after Gunnison Dr (which will be on your right). I recommend taking a few minutes and looking at Maps before you head out to make sure you know where you're going. ***(So walk with me...)* Restrooms and Water Fountains** There are a few port-a-potties sprinkled throughout the park (including two at the parking lot we'll be meeting at), and the Park Office, roughly in the center of the park and which we'll pass twice on this hike, has restrooms and a water fountain. This is the only water fountain, though, at Quarry Trails. ***(At Trails Quarry!*)** **After the Hike** Afterward, we'll head over to [Johnnie's Tavern](https://johnniestavern614.com/) for [drinks](https://www.google.com/maps/place/Johnnie's+Tavern/@39.993202,-83.0903169,3a,75y,90t/data=!3m8!1e2!3m6!1sCIABIhAulLarLYZC3hY_vRGwoakV!2e10!3e12!6shttps:%2F%2Flh3.googleusercontent.com%2Fgps-cs-s%2FAG0ilSzkwnMN29-lrgzp50Rzeaq5jXCGM1xLS1poH0Mc52-E9NYBvdS99ei7zGmlAYJZyk8OeNW5YvS7agj8M2Bom4ri1m_-NcJiT-LQUDphkS-SB5Vq8JhO-8NSP-_m80HeLz4-pGhjrwhuBKSv%3Dw146-h195-k-no!7i4284!8i5712!4m7!3m6!1s0x883891c4d61ba04d:0x5134f225cbf678bf!8m2!3d39.9932439!4d-83.0902078!10e9!16s%2Fg%2F11c1p57s3t?entry=ttu&g_ep=EgoyMDI1MTExMi4wIKXMDSoASAFQAw%3D%3D) and [food](https://www.google.com/maps/place/Johnnie's+Tavern/@39.993202,-83.0903169,3a,75y,90t/data=!3m8!1e2!3m6!1sCIABIhB5lD4Uly_4O9BjNH4r3ywB!2e10!3e12!6shttps:%2F%2Flh3.googleusercontent.com%2Fgps-cs-s%2FAG0ilSy7tQcc7CtCeuUAKwEVJoxtOs8Ycohjy3mGZZOC_kJVdB8wEaGuC4-p5z_jxn2JnpmSEkh_HG7Aok_ZPEgmK57rEBqNIPH8J5tiyAP5vbrRYkUso_fKTkW5vJc47UusNoGiRzs2Vf0m1JcV%3Dw146-h195-k-no!7i4284!8i5712!4m7!3m6!1s0x883891c4d61ba04d:0x5134f225cbf678bf!8m2!3d39.9932439!4d-83.0902078!10e9!16s%2Fg%2F11c1p57s3t?entry=ttu&g_ep=EgoyMDI1MTExMi4wIKXMDSoASAFQAw%3D%3D).

**People Analytics 101: Making Sense of Compensation Data** Compensation data is one of the most widely used and widely misunderstood forms of people analytics. The session will cover where compensation data comes from, including market pricing data, internal payroll data, and benchmarking sources, and how companies think about structuring and analyzing that information. We will explore how compensation data is leveraged to set salary ranges, manage internal equity, support hiring and retention, and align pay with business strategy. A portion of the session will address common data challenges and limitations, such as market noise, inconsistent job matching, and incomplete datasets, while keeping the primary focus on practical use rather than technical depth. The session will also look ahead at where the space is going, including the growing impact of pay transparency laws, expanding pay equity requirements, and emerging regulations in the US and Europe that require organizations to report on gender and pay gaps. The goal is to give attendees a clear mental model for how compensation analytics works today and why getting it right is becoming increasingly critical. (note: we are back at Rev1 this month!) **About Our Speaker** [Alex Moore](https://www.linkedin.com/in/alexscottmoore/) is the founder of [Moore Cooperative](https://moorecooperative.com/), where he advises organizations on compensation strategy, pay equity, and people analytics.

Dale Gnidovec, Curator of the Orton Hall Museum of Geology at The Ohio State University, will be presenting a program he has wanted to share with us for a long time: Plate Tectonics. His description of his program: Continents on the move - Nothing in Earth history makes sense without moving continents - it tells us why mountains, volcanoes, minerals, and fossils are where they are. This talk examines the evidence for continental drift, why it was disbelieved, and explains how the more-encompassing theory of plate tectonics was developed and eventually proven. Dale is an energetic, incredibly knowledgeable, and very entertaining speaker and this will be another wonderful program by Dale. Hope to see you there! Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid.

### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases. Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI. Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem. Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.
