We’re heading out for a beautiful 20 km loop hike from Afferden through the gorgeous Nationaal Park De Maasduinen. This route takes us through a striking Limburg landscape of forest, sandy paths, open heathland, river dunes, and wide views. Along the way, we pass the ruins of Kasteel Bleijenbeek and climb an uitkijktoren for a panoramic view over the Maasduinen landscape. One of the special features of this hike is that we cross the Maas river twice by small ferry. These crossings give the route an extra sense of adventure and connect the Maasduinen landscape with the village side of the river. After one of the crossings, we continue to the village of Vierlingsbeek, where we’ll take our longer break for a drink. After the break, we make our way back toward Afferden, completing a varied loop through forest, heathland, castle history, river scenery, ferry crossings, and quiet Limburg countryside. A hike with forest energy, open heathland, castle ruins, a lookout tower, two Maas river crossings, and a relaxed village drink stop. **📍When and where to meet?** We’ll meet at 11h15 at Busstop "Afferden, Veer naar Sambeek" https://maps.app.goo.gl/kcg4hBvRsHoUjBSa6 ⏰ **We start walking a few minutes after meeting up** We don’t wait for latecomers, as we have a long route ahead and want to enjoy the full day properly. **🚗 Coming by car?** Please check your parking options beforehand so you arrive on time. **⏸️ Planned Breaks** After **4 km:** break at watchtower (5 min) After **7 km:** Having a lunchbreak at ruins of Castle Bleijenbeek (25 min) After **13 km:** Ferry over the Maas After **14 km:** Drinks at bar in Vierlingsbeek (50 min) After **20 km:** Ferry back over the Maas (bring small change to pay the ferry) I still need to confirm or make a reservation at the bar. **💸 Payment** Please pay as soon as you sign up: To keep things fair for everyone, if we don’t receive your payment within 48 hours, we will need to remove you from the participant list.

This hike is one you don’t want to miss! It offers a lot of variety on a relatively short distance. From train station Rhenen, we will cross the river and walk along it for a while, until we cross it again by ferry, taking us to the beautiful wetlands of the ‘Blauwe Kamer’, where we might encounter all kinds of wildlife. After a break, we will continue to climb the Grebbeberg, a 52 meter peak in the hilly forest, towering above the river. We will then return to Rhenen, with the option of visiting this pittoresque old town. **Where to meet**: we will meet at **10.30am** at train station Rhenen. This train station can be reached by Sprinter train from Utrecht Centraal. **This hike is fully booked.** [You may register for a place on the waitlist on my website.](https://rewildyourself.nu/dutch-nature-hikes/)

Over a billion documents processed. Millions of Veterans impacted. Hundreds of thousands of employee hours saved. Faster decisions. Greater accuracy. More benefits in the hands of our disabled Veterans. We created Smart Search, the world’s largest consumer of Amazon Textract, right when GenAI began reshaping what’s possible. Since then, we’ve built a suite of AI‑driven solutions that transform this data into real, measurable outcomes—accelerating benefits decisions for our Nation’s Veterans. Join us for a focused conversation on how an outcome‑driven approach to AI is helping us boost accuracy, streamline workflows, and deliver faster results for those who have served. This is a follow up to the AWS re:Invent 2023 "Intelligent Document Processing with Gen AI for Public Sector" presentation.

Join the Columbus AI community for a special event. **Battle of the Personal Agents** is your chance to see what people are actually building with AI agents and personal automation systems. Whether you’re running OpenClaw, Hermes, or a completely custom solution, bring your agent and show the community how it works. We’re interested in real-world implementations: the problems your agent solves, how you use it day-to-day, how it’s hosted and managed, how you built it, and why you’ve chosen to keep using it. Live demonstrations are encouraged, so be prepared to show your code, architecture, workflows, and your agent performing real tasks. This is less about polished presentations and more about sharing practical experience, comparing approaches, and learning from one another. If you’d like to present, please contact Chris Slee (via meetup) before the event so we can allocate enough time for everyone’s demonstrations. Come ready to show what you’ve built, discover what others are doing, and maybe find a few ideas worth taking home. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
