Learning Finnish in Finland can be difficult because Finns tend to switch to English. That is one of the reasons people like our Finnish language café: you get to practice Finnish with Finns :) The events are completely free and there is always a native speaker to facilitate the conversation and to help find the right words. The coffee is good too ☕😋🇦🇹 Tervetuloa!

Pay the **5 € board gaming fee** to the bar at the counter when you arrive. You must be at least 18 years old to enter [Arkade](https://www.arkade.fi/). We play in English and the game rules are taught before starting play, unless everyone is already familiar with the game. No previous experience with board gaming required. The venue has a great board game library, the host and other players usually bring their own games too: our selection varies weekly. We're a very casual group so you're welcome to arrive early or late and join whatever game is starting up, there is no attendance tracking, or welcoming process. The bar has alcoholic drinks, mocktails, and soft drinks available as well as some snack foods. They've been okay with people ordering food to the bar with meal delivery services. If you are feeling sick, please stay home.

Join our partners Watermark Woods Native Plants, Loudoun County Public Library (LCPL), and Birch Tree Bookstore for the Read! Plant! Grow! Book Club, which focuses on native plants, sponsored by Loudoun Wildlife Conservancy and LCPL. At this meeting we’ll discuss the book Animal, Vegetable, Miracle by Barbara Kingsolver. Both memoir and journalistic investigation, this book explores how the Kingsolver family took on a new challenge: to spend a year on a locally -produced diet, paying close attention to the provenance of all they consume. Concerned about the environmental, social, and physical costs of American food culture, they hoped to recover what Kingsolver considers our nation’’s lost appreciation for farms and the natural processes of food production. You can either buy the book from Birch Tree Bookstore or contact Allison Forbes at [Allison.forbes@loudoun.gov](mailto:Allison.forbes@loudoun.gov) to borrow a copy of the book at the library. There are two ways to participate: attend the event online via the library website or [sign up to participate in person at Birch Tree Bookstore](https://www.birchtreebookstore.com/event-details/read-plant-grow-2026-02-24-18-30). ***Questions:*** *Contact [info@loudounwildlife.org](mailto:info@loudounwildlife.org)*.

Face-to-face Role Playing Game Session

This training is designed for real estate agents who want to learn how to play the Agent Investor game. The goal of this training is to help you flip your income into ownership. ━━━━━━━━━━━━━━━━━ **Investors move fast. Most agents don’t.** If you can’t evaluate a deal quickly and confidently, you lose credibility—and the opportunity disappears. Deal or Disaster teaches a simple, repeatable framework to determine in minutes whether a deal prints money or burns it. In this session, you’ll learn a 5-minute investment evaluation system that works across flips, rentals, BRRRRs, wholetails, and creative deals. The goal isn’t perfection—it’s speed, clarity, and credibility. We’ll break down: * How to identify the investor’s true goal before running numbers * A fast, reliable method to estimate ARV with confidence * How to calculate the real all-in acquisition cost * Simple heuristics to ballpark rehab and improvement costs * The key metrics that reveal whether a deal works—or should be killed You’ll also learn the most common red flags that signal bad deals, thin margins, and hidden risk, so you know when to pause or walk away. When you can analyze deals in minutes, you earn authority, build trust, and become indispensable to investors. Speed creates opportunity—and opportunity creates repeat business. If you want to move from real estate generalist to trusted investment strategist, this session gives you the framework to do it. ━━━━━━━━━━━━━━━━━ **Did you miss it?** [Watch all GRID Reston event playback on YouTube](https://www.youtube.com/playlist?list=PLOTh5kxLLJI1G3VH6Pqhlhu0uTA8yrdpi) ━━━━━━━━━━━━━━━━━ **Join the GRID Facebook Community** [Join the online GRID community here](https://www.facebook.com/groups/gridinvestor) to post deals, ask questions, and connect with other investors across the globe.
