With warm & good weather on the horizon again, it's time again to get more picnic-y & outdoors-y 🌄 For this new season, let's revisit the old picnic gathering formula, but add into the night vibe & spicy dance theme (in this case tango, because other dances are oversaturated with events 😊) The premise: A picnic gathering starting from 19:00 & ending 23:00 sharp Since it's evening vibes, BYO food/drinks/games still applies but think time appropriate (don't go big on alcohol though!) Dancing aspect, music starts 20:00 & ends 23:00 sharp! Exact location in Griftpark: To be concluded, but assume close to where the meetup event location currently is set at Additional notes for the tango aspect: * you're very much welcome to join in & dance, even with no experience. I can show you a thing or two so you can get a taste & give it a go 😊 Depending on how many, either via a quick group tryout or I help you out individually * The tango aspect of the event is through the Utrecht Tango Cafe Milonga community (also organized by Constantinos) More info --> https://www.utrechtcafemilonga.com If you have any further questions, feel free to message the host Depending on the time & weather, and whether people are up for it, follow-up drinks can always follow later that day. To those interested, I hope to see you there! 😄

'THE SYMPATHIZER' by Viet Thanh Nguyen 'The winner of the 2016 Pulitzer Prize for Fiction, as well as seven other awards, The Sympathizer is the breakthrough novel of the year. With the pace and suspense of a thriller and prose that has been compared to Graham Greene and Saul Bellow, The Sympathizer is a sweeping epic of love and betrayal. The narrator, a communist double agent, is a man of two minds, a half-French, half-Vietnamese army captain who arranges to come to America after the Fall of Saigon, and while building a new life with other Vietnamese refugees in Los Angeles is secretly reporting back to his communist superiors in Vietnam. The Sympathizer is a blistering exploration of identity and America, a gripping espionage novel, and a powerful story of love and friendship.' ***Please read the book and join us for a lively discussion (in English) about the contents during our afternoon book club meeting.*** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **PLEASE NOTE:** This is an IN-PERSON event in Amersfoort, The Netherlands.

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.

The only Metro Park with a fire tower! **History** [Scioto Grove Metro Park](https://www.metroparks.net/parks-and-trails/scioto-grove/) officially became the 19th park in the Columbus and Franklin County Metro Parks system when it opened to the public on May 6, 2016. Located along a scenic bend of the Scioto River in Grove City, just south of Columbus, the 620-acre park was designed to blend preservation with modern recreation. Long before it became a park, this river corridor served as a vital footpath and trade route for Indigenous communities. Decades later, the mature forests and dramatic river bluffs caught the eye of conservationists looking to expand regional green spaces. The grand opening was a major milestone, drawing over 19,000 visitors in its very first weekend. The creation of the park was made possible through a sequence of land acquisitions and strong community partnerships. In October 2009, Franklin County voters approved a critical property tax levy that funded the initial purchase of 66 acres. Shortly after, the City of Grove City generously donated nearly 193 acres of land, previously known as Talbot Park, to anchor the project. Additional parcels were acquired using state grants from the Clean Ohio Conservation Fund, successfully closing the gap between properties by December 2012. This collaborative funding model ensured that pristine wilderness areas remained completely protected from commercial development. From its inception, the park aimed to introduce innovative amenities to the regional park system, most notably the concept of "urban backpacking". Through a key partnership with the outdoor gear retailer REI Co-op, the park established the scenic REI River Trail. This trail features five rustic, reservation-only campsites along the river, specifically designed to give newcomers a safe place to practice backpacking close to home. Additionally, planners prioritized making the park fully pet-friendly, allowing leashed dogs across all trails and areas. This open-pet policy uniquely distinguished Scioto Grove from many other traditional Columbus Metro Parks. As the park grew in popularity, community members established special commemorative landmarks to honor local lives. In June 2019, a dedicated memorial garden was unveiled near the park entrance in memory of Reagan Tokes, an Ohio State University student. The serene space features a central pond bordered by bright blue flowers, representing her favorite color. A primary buckeye tree stands alongside a dedicated plaque, surrounded by four additional buckeye trees to represent her immediate family members. This addition transformed a portion of the park into a meaningful place for community reflection, healing, and peace. The historical depth of the park took a significant leap forward with the relocation of a massive piece of Ohio history. In August 2023, Metro Parks officially unveiled the Keystone Forest Lookout Tower, which had been carefully moved from Jackson County, Ohio. Originally constructed in 1942 by the Aermotor Windmill Company, the 82-foot-tall metal structure spent decades guarding southern Ohio’s vast forests from devastating wildfires. Workers painstakingly disassembled, re-galvanized, and reassembled the historic landmark at Scioto Grove. Today, visitors can climb its 111 steep steps to experience a panoramic view stretching all the way to the downtown Columbus skyline. **Map of the Park** Here is a [map of Scioto Grove](https://www.metroparks.net/wp-content/uploads/2026/05/SGR-map_1980px_2026.jpg). **Summary** We will hike around 5 miles on the Overlook, REI River, Mingo, and Arrowhead Trails. While the configuration of the trails can lead us to occasionally taking longer hikes than at other parks, Scioto Grove is not generally a very strenuous place to hike. If you use hiking poles and inadvertently forget them, this is not a park where you're likely to end up caring that much. That said, Scioto Grove is one of the better Metro Parks for hiking as well as other things. They are the only Metro Park with five camping areas where you can literally pitch a tent and sleep for the night. You must contact the park and reserve these in advance; they are however free. **Where We'll Meet** We'll meet at the Arrowhead Picnic Area, near the restrooms and playground. Arrowhead is the main picnic and parking area of the park, and it also has the only water fountain at Scioto Grove. **After the Hike** Afterward, we will head over to [Grove City Brewing](https://www.grovecitybrewery.com/) for [drinks and food](https://www.grovecitybrewery.com/menu). They have pretty good hamburgers. I was mortified to discover that I've never had their [Grove City Hooyah](https://www.beermenus.com/beers/486553-grove-city-hooyah) before, but I will correct that during this event. The actual address of the brewery is [3946 Broadway, Grove City, OH 43123](https://www.google.com/maps/place/3946+Broadway,+Grove+City,+OH+43123/@39.8836912,-83.0919635,16z/data=!3m1!4b1!4m6!3m5!1s0x88389b3a28d0f4ad:0x3d85c41f608406c6!8m2!3d39.8836912!4d-83.0919635!16s%2Fg%2F11g8dh6h1_?entry=ttu&g_ep=EgoyMDI0MTAwOS4wIKXMDSoASAFQAw%3D%3D). We should be there by 5 if you can't make the hike and just want to join us for drinks.
