Mimic the great skaters who gracefully carve an ephemeral numeral “8” in the ice—but instead of skates, use the steel wheels of the Metro system! We’ll start at Metro Center, make our way to Ft. Totten on the Red line, transfer (in a very cool way) to the Yellow or Green lines; then go down to L’Enfant Plaza, where we’ll switch to the Blue, Orange or Silver lines to take us home to Metro Center and complete our ”8”. Then off to Potbelly Sandwich Shop for lunch and reflection on our feat!

**Dust off those old classics in your binders and experience Yu-Gi-Oh! as it never was.** **Cookie-cutter deck lists, begone! Constant board wipes, begone! Tier-1 tyranny, begone! Get ready for the format you never knew you needed. If you’ve been utterly overwhelmed by the speed of the modern metagame, rejoice! If you’ve long suppressed the itch to bamboozle your buddies with obscure Traps none of them have heard of, your time has finally come! If you’ve always wondered what a format with 100 viable decks looked like, then prepared to be amazed, utterly.** **The AINW card pool contains every release originally printed before the TCG set, Duelist Alliance. Please note, this is not a true Retro format. We’ll be using updated card text for many cards formerly on Konami's Forbidden & Limited List. The inclusion of newer errata is not meant to tarnish the legacy of certain cards. Their inclusion is meant to maximize the number of viable options whilst preventing dangerous sequences such as Divine Wind FTK.** **Click the link to view the rules and restrictions below:** **[https://docs.google.com/document/d/1sW3SkG5XNor-W-gRvwuvCWwuWeMelt-KkwpHYpOOwO4/edit?usp=sharing](https://docs.google.com/document/d/1sW3SkG5XNor-W-gRvwuvCWwuWeMelt-KkwpHYpOOwO4/edit?usp=sharing)** **Many of these parameters you’ll likely find surprising, sacrilegious even. Just keep an open mind and give my format a try. I think you’ll be surprised by the sheer number of strategies that are actually viable. I didn’t set out to create a list that was perfect. But, I do believe I have succeeded in crafting one that is actually CONSISENT in what it bans, something that Konami's Forbidden & Limited list has never been.**

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.

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.
