**Doing KPIs Right: a KEY to Analytics (and AI!) Impact!** On the one hand, KPIs are such a Business 101 concept that it may seem a little silly to dedicate an entire session to the topic. On the other hand, KPIs get handled so poorly so often that a case could be made that this meetup could just be one of the most impactful sessions of the entire year! We’re starting off the year at a new location: [COhatch Upper Arlington](https://www.cohatch.com/locations/columbus/upper-arlington/) but with a familiar speaker, Tim Wilson! We’ll be back at Rev1 in February, when the speaker will presumably not be Tim. Tim will make the case that effectively measuring performance of projects, campaigns, and initiatives (and even meetups!) should be a foundation for any data analytics program. Topics covered will include: the “two magic questions” of performance measurement, how to help business partners distinguish between outcomes and outputs, and effective tactics for collaboratively establishing KPI targets. He will also stick his neck out by demonstrating some of these techniques in real-time by measuring whether his talk lives up to the promise of this description! All CBUSDAW events are free thanks to our 2026 Sponsors: Clarivoy, Conductrics, What Box Consulting Group, and Piwik PRO. Check out [cbusdaw.com](https://cbusdaw.com) for more information.

**History** [Blacklick Woods Metro Park](https://www.metroparks.net/parks-and-trails/blacklick-woods/), established in 1949, holds the distinction of being the first Columbus Metro Park. Its creation stemmed from a post-World War II push to preserve natural areas amid rapid suburban growth. The land, originally farmland and woodlots along Blacklick Creek, was acquired by the Columbus Metropolitan Park Board through donations and purchases. Early efforts focused on basic trail development and reforestation to combat erosion. The park's name derives from the creek, which early settlers called "Black Lick" due to its dark, mineral-rich waters. By the 1950s, it served as a model for the expanding Metro Parks system. In the 1960s, Blacklick Woods expanded significantly with additional land acquisitions, reaching over 600 acres. A golf course was added in 1964, one of the first public courses in the region, designed to generate revenue for park maintenance. Native American artifacts, including arrowheads from the Adena culture, were discovered during construction, highlighting the area's prehistoric use as hunting grounds. The park introduced interpretive programs to educate visitors on local ecology and history. Flood control measures along the creek became a priority after heavy rains caused damage. These developments solidified its role as a recreational hub. The 1970s and 1980s brought environmental awareness, leading to habitat restoration projects at Blacklick Woods. Invasive species were removed, and native wildflowers were planted in the meadows. A nature center opened in 1976, featuring exhibits on wetlands and forests. The park's slate-covered bridge, a remnant of 19th-century infrastructure, was preserved as a historic feature. Birdwatching gained popularity with the addition of observation decks. Community volunteers played a key role in trail maintenance and cleanups. During the 1990s, Blacklick Woods underwent major upgrades, including paved multi-use trails for biking and hiking. The Walter A. Tucker Nature Preserve, a 53-acre old-growth forest within the park, was dedicated in 1995 to protect rare beech-maple woodlands. Educational partnerships with local schools introduced field trips on topics like stream ecology. The golf course was renovated to improve playability while minimizing environmental impact. Annual events, such as the fall festival, drew thousands to celebrate the park's natural beauty. These enhancements balanced recreation with conservation. In the 21st century, Blacklick Woods has adapted to increasing visitation with sustainable practices. Solar panels were installed at facilities in the 2010s to reduce energy costs. The park now spans 643 acres, offering diverse habitats from wetlands to uplands. Recent initiatives include pollinator gardens and prescribed burns to maintain prairie areas. It remains a flagship for the Metro Parks, inspiring similar preservations system-wide. Ongoing archaeological surveys continue to uncover traces of early inhabitants. **Map of the Park** Here is a [map of Blacklick Woods](https://www.metroparks.net/wp-content/uploads/2025/10/BLK-map-May-2025-with-extended-greenway_1980px.jpg). **Summary** For this event, we will hike about 4.5 miles by doing a couple loops of the Buttonbush, Tucker, Maple Loop, and Beech trails. Blacklick Woods is a very nice park, but it is generally flat and not strenuous, so this will be one of the easier hikes that we do. **Where We'll Meet** Drive all the way to the back of the park to the parking lot that is nearest the Nature Center. There are restrooms here next to the Canopy Walk. We'll meet near these restrooms. Speaking of the [Canopy Walk](https://www.metroparks.net/blog/canopy-walk-is-your-gateway-to-the-sky/), it's not officially part of the event this time. However, if interested people want to freelance and check it out after the hike (before heading to the brewery), that's okay. **After the Hike** After we're done with the trails, we'll head to [Prost Beer & Wine Café](https://prostcafe.com/) for drinks and [food](https://prostcafe.com/reynoldsburg-prost-beer-and-wine-cafe-food-menu). The actual address of the brewery is [7354 E Main St, Reynoldsburg, OH 43068](https://www.google.com/maps/place/7354+E+Main+St,+Reynoldsburg,+OH+43068/data=!4m2!3m1!1s0x8838648cfb8d2dbb:0x545274bab130e9bb?sa=X&ved=1t:242&ictx=111), and we should be there by 5:00 if you just want to do that and skip the hike.

For January, we’re reading Migrations by Charlotte McConaghy. For fans of Flight Behavior and Station Eleven, a novel set on the brink of catastrophe, as a young woman chases the world's last birds--and her own final chance for redemption. Franny Stone has always been a wanderer. By following the ocean's tides and the birds that soar above, she can forget the losses that have haunted her life. But when the wild she loves begins to disappear, Franny can no longer wander without a destination. She arrives in remote Greenland with one purpose: to find the world's last flock of Arctic terns and track their final migration. She convinces Ennis Malone, captain of the Saghani, to take her onboard, winning over his eccentric crew with promises that the birds will lead them to fish. As the Saghani fights its way south, Franny's dark history begins to unspool. Battered by night terrors, accumulating a pile of unsent letters, and obsessed with pursuing the terns at any cost, Franny is full of secrets. When her quest threatens the safety of the entire crew, Franny must ask herself what she is really running toward--and running from. Propelled by a narrator as fierce and fragile as the terns she is following, Charlotte McConaghy's Migrations is both an ode to our threatened world and a breathtaking page-turner about the lengths we will go for the people we love.

2026 may be the last year many developers write code by hand. We need coding agents to solve complex problems in production codebases, but vibe coding alone won’t get us there. Vibe coding is all gas, no brakes. It burns up the context window until the agent slips on its own slop. You can go fast at first, but the more you stuff into the context window, the more tangled its outputs get. While the industry is rapidly increasing code generation speed, we still have to understand, review, merge, and maintain what gets shipped. This talk featuring Michael Geiger will outline how coding agents (Claude Code + Gas Town) work and a framework for orchestrating them to solve complicated problems in complex codebases. It’s about steering the model: doing the research to align intent, planning the approach up front, implementing in parallel steps, and breaking early. Human judgment still matters, but it should be spent on high-leverage decisions: what to build, what to forbid, and “what is quality?”, not cleaning up slop. Attendees will leave with a checklist to identify workflow and environment gaps that hold agents back, so you and your team can ship higher-quality software starting tomorrow.

Welcome to Drunken Philosophy, a casual, curious, social discussion club. Optional topic for this meet up: Is life a dream? Dreams feel real while they last. Could life work the same way? How do we know we’re awake, and what follows if we can’t be sure? Let’s kick that around over a around of drinks: • What makes something feel real: continuity, shared evidence, or meaning? • How would you tell you’re awake (reality checks, memory, other people)? • If life is dreamlike, what becomes of free will and responsibility? • Is identity a story we keep telling—who’s the narrator? • Are we author, actor, or audience in our dreams and how would you tell? • Does art/film reveal reality or replace it? No lectures. Friendly crowd. Drop in for one drink and stay if it’s fun.
