This session will explore the history of the Cuban Revolution and Cuba’s long-standing role in supporting African liberation struggles and Global South development. We will examine why Cuba has been treated as a threat to Western hegemony, the ongoing impact of the U.S. blockade, and Cuba’s model of people-centered systems in healthcare, education, and participatory governance. The discussion will highlight Cuba’s internationalist commitments— including the deployment of over 600,000 doctors across Africa and the Global South—and reflect on what it means for African people and movements today to stand in solidarity with Cuba. Together, we will consider the broader connections between anti-imperialism, internationalism, and the collective struggle for self-determination. This is a hybrid event, with the option to participate in-person or via Zoom. Register here for either option: https://africansolidaritywithcuba.eventbrite.com *Food will be provided!*

Does it feel like the world is ending? Stop doomscrolling and try some vigorous outdoor activity! We are NPS Weed Warriors and Arlington Regional Master Naturalists and you should volunteer with us on Sunday, March 15 to learn about nature and remove invasive plants from everyone's favorite urban island. Meet us at the entrance to the bridge (on the parking lot side, look for the sign) at 10:00 and bring your garden gloves and loppers/pruners if you have them. If not, we can provide gloves and tools. Wear long sleeves and pants and don't forget a water bottle. We will have tasks ranging from easy (cutting English ivy and honeysuckle vines from trees) to hard (sawing down bush honeysuckle). Parking at TRI can be tight if it's a pretty day. When the parking lot is full, you can park in Rosslyn and take the trail down. If you can bike or walk or take public transit, that's wonderful. We'll see you there! Erica, Stephanie, and Heidi P.S. If you can't wait until then to RIP (Remove Invasive Plants!), go here to find more volunteer opportunities in Arlington parks: [Volunteer to Restore Native Habitat – Arlington Regional Master Naturalists (armn.org)](https://armn.org/volunteer-opportunities/)

This hike was originally planned for March 2020. Once again it's safe to visit our fictional grandmother’s house to celebrate Pi(e) Day! This year on 3.14, to our fictional grandmother's house we'll go as we rejoin the story, six years later. Our easy 5.5-mile hike is travels in an extremely unique environment where nutrient-poor soil does not allow for much to grow. Soldiers Delight Natural Environment Area (NEA) is comprised of 1,900 acres of serpentine barren. The area has over 39 rare, threatened, or endangered plant species as well as rare insects, rocks and minerals, unique to this world. Bring water, lunch, snacks, sturdy footwear, any round-shaped treats you may wish to share (optional), and $12 for transportation and the Adventuring trip fee. Meet at 9:00 a.m., at the Greenbelt Metro Station entrance (in the big concrete plaza) of the station to form carpools. On the way, we'll make a stop for any last-minute snacking needs. After the hike, the group may opt for a brewery stop at Notch 8 Brewery to refresh us. *\*\*-> Please [click here](https://adventuringlgbtq.com/Adventuring_Release_Form.pdf) to review our release form.

The pickleball courts are situated on the far side of the playground, past the swing sets and picnic area. These courts (are] strictly on a first-come, first-served basis, and we do not offer reservation for public use. The courts are frequently unoccupied, but sometimes few people utilize the courts. We've created a WhatsApp group for our Meetup community to help everyone stay connected and get event updates more quickly. It’s a great way to share important info, coordinate plans, and keep each other in the loop about upcoming meetups. Feel free to join so you don’t miss out on any of the fun! https://chat.whatsapp.com/Bw0vxcNKRC1CeHixU41wTG

BEVERAGES: BYOB DRINKING: You can bring your own booze (if you drink), just no drinking and driving like some ignorant person from the 80s and 90s, when Uber didn’t exist! 5 USELESS FUN FACTS ABOUT ST. PATRICK’S DAY (taken directly from https://www.history.com/.amp/news/st-patricks-day-facts) 1. The Real St. Patrick Was Born in Britain Much of what is known about St. Patrick's life has been interwoven with folklore and legend. Historians generally believe that St. Patrick, the patron saint of Ireland, was born in Britain (not Ireland) near the end of the 4th century. At age 16 he was kidnapped by Irish raiders and sold as a slave to a Celtic priest in Northern Ireland. After toiling for six years as a shepherd, he escaped back to Britain. He eventually returned to Ireland as a Christian missionary. 1. There Were No Snakes Around for St. Patrick to Banish from Ireland Among the legends associated with St. Patrick is that he stood atop an Irish hillside and banished snakes from Ireland—prompting all serpents to slither away into the sea. In fact, research suggests snakes never occupied the Emerald Isle in the first place. There are no signs of snakes in the country’s fossil record. 1. Leprechauns Are Likely Based on Celtic Fairies Leprechaun is commonly associated with St. Patrick’s Day. The original Irish name for these figures of folklore is “lobaircin,” meaning “small-bodied fellow.” Belief in leprechauns likely stems from Celtic belief in fairies— tiny men and women who could use their magical powers to serve good or evil. 1. The Shamrock Was Considered a Sacred Plant The shamrock, a three-leaf clover, has been associated with Ireland for centuries. It was called the “seamroy” by the Celts and was considered a sacred plant that symbolized the arrival of spring. According to legend, St. Patrick used the plant as a visual guide when explaining the Holy Trinity. 1. Corned Beef and Cabbage Was an American Innovation The meal that became a St. Patrick’s Day staple across the country—corned beef and cabbage—was an American innovation. While ham and cabbage were eaten in Ireland, corned beef offered a cheaper substitute for impoverished immigrants. Irish-Americans living in the slums of lower Manhattan in the late 19th century and early 20th, purchased leftover corned beef from ships returning from the tea trade in China. The Irish would boil the beef three times—the last time with cabbage—to remove some of the brine. Read more about Irish-American traditions here. ANOTHER USELESS BULLET TO SEE IF YOU READ THIS FAR: Damn, details must be important to you! That’s sooooo not me, but I love you detailed f*cker! See you at the FAF killer St. Patrick’s day PARTY! And the following week we have the dress up for the wrong party party, where we will celebrate our cohost who is the kindest, most generous, loving fun person on earth, Amanda‘s 50th birthday. This is going be super FUNNNN. Why are you not signing up for that as well?!!! Get on it. Let’s get your head in the game now brah…it’s 2026 the year of the fire horse!

A few years back, Amazon created a new TV show about the Tom Clancy character Jack Ryan. Somewhat infamously, [Jack Ryan's Morning Commute](https://dcist.com/story/18/09/04/jack-ryans-commute-to-work-makes-ab/) makes no sense. So this walk is inspired by the route he should've taken Part 1 (9.5 miles) - https://maps.app.goo.gl/2pmXJaixbXQxnvfv8 1\. Foggy Bottom metro 2\. Potomac Boat club 3\. Chain Bridge 4\.

McLean Metro **Millage:** \~16.0 miles **Start Location:** Foggy Bottom Metro Station **End Location:** McLean Metro Station **Time:** 10:00 AM - 4:00 PM **Terrain:** This will be have a solid amount of uphill (\~700 feet) elevation gain) with a mix of paved, gravel, and trail surfaces

COST: Green Spring has a parking fee which we will collect together because they consider us a “group” with different fee rules. Therefore, DO NOT put parking fee in parking lot collection box. Instead, please bring some cash for the GROUP fee (dollar bills or a fiver) to our start point. DESCRIPTION: Join us on a slowish walk over gentle hills with stops (up to two miles in about two hours) at Green Spring Gardens, Alexandria, to enjoy the waning wonders of winter (and even last autumn) and the signs of spring.(Unfortunately, the mulched trails and slopes are not wheelchair accessible nor suitable for those with walking difficulties.) Experience nature in a leisurely way, and awaken your senses. Before trees leaf out, we still get our longest scenic views, evergreens pop, and groups of bare trees are like sculpture gardens. Delight in the rush of spring water and colors and textures of early flowers. In the Glass House conservatory, preview what will become the colorful late-spring planted gardens. WHAT WE'LL DO: We will meander up to 2 miles in about 2 hours within Green Spring Gardens (with opportunities to stop, engage and wonder) and end up back at the visitors center. YOUR GUIDE: Adrienne Betancourt is an educator (with a career in adult education and college programs.) She completed the Maryland Natural Naturalist 60-hour course and has continued to study natural history, with experience leading programs and walks for kids, families, and adults.

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Our March speakers are Molly Gaines and Zack Parrish, co-organizers of the Secular Education Association: They will share their story of how a small group of Ohio parents grew into a national organization tracking released-time religious instruction and other church–state issues in public schools. The presentation will cover SEA’s early wins and hard lessons, what we’re seeing nationally right now, and how local advocates can play a meaningful role in protecting public education. Attendees will leave with a clearer understanding of the landscape — and practical ways to get involved. Going forward our meetings will be hybrid.
