Let's play monopoly in the open area called "The Landing" at the Crystal City Shops. The Landing is right at the Crystal City metro stop and, if you're driving, there is free parking [on weekdays after 4pm and weekends] in the garage. See below for more details. With many tables for games and nearby eateries in the mall, it is a fantastic location for playing board games. We'll be starting at 3:00 pm, but feel free to wander in whenever you'd like.Please RSVP to play. If you'd like to start earlier, feel free to mention that in the comment section. If everyone is already in the middle of games when you arrive, please don't hesitate to pull up a chair and watch a game in progress. We will play a minimum of 3 and a maximum of 6 people at each table. This is a friendly group of competitive and non competitive players and our different backgrounds and different experiences of Monopoly make for interesting conversation during the games. If you're taking the metro, exit at Crystal City and you can walk to The Landing without having to go outside. When you come up the first set of escalators, turn right to enter the underground shops and then turn right at Rite Aide. Continue straight and The Landing will be the large open seating area on your right, next to San Antonio Bar & Grill and Subway. If you're driving, parking is free in the garage. Enter the garage for 1750 Crystal Drive on 18th Street and take a ticket. (You'll need this to exit, but there's no charge). Take the elevators up to Level S. The Landing is the large open seating area next to San Antonio Bar & Grill and Subway. If that parking garage is full, exit the garage and turn left on 18th and left again on Crystal Drive. A second parking garage is located on Crystal Drive between 18th Street and 15th Street. This is a link to a map of the Crystal City Shops: http://www.thecrystalcityshops.com/ The Landing is in the yellow section on the map near the San Antonio Bar & Grill and Subway.

THIS CLASS IS OFFERED THROUGH CAPITAL PHOTOGRAPHY CENTER **PLEASE REGISTER WITH CAPITAL PHOTOGRAPHY CENTER, NOT MEETUP!** https://capitalphotographycenter.com/classes/class/2026-04-19-sculpting-photos **Sculpting Photos** The sculptures in the west wing National Gallery of Art offers photographers a unique creative challenge: The art is already shaped by light, form, and intention. In this class we will explore how photography can re-imagine three-dimensional works through thoughtful observation and creative choices. By paying close attention to light, shadow, texture, and perspective, photographers can reveal new interpretations of sculptures, highlighting details, moods, and relationships that may not be immediately visible to the naked eye. Through guided looking and hands-on practice in the galleries, students will learn how camera position, framing, depth of field, and timing transform solid, static objects into dynamic photographic images. Whether isolating a gesture, emphasizing scale, or experimenting with abstraction, this class encourages photographers to move beyond documentation and toward personal expression, using sculpture as a powerful starting point for visual storytelling. Whether you’re new to photography or looking to deepen your practice, this class invites you to see the sculpture and your creative process in fresh ways. In this class you will learn to: 1. Develop observational skills by learning to analyze sculpture in terms of form, space, light, and texture, and translating those observations into intentional photographic choices. 2. Explore creative photographic techniques such as framing, perspective, and selective focus to reinterpret sculptures and create expressive, original images in an indoor museum setting. 3. Build visual storytelling skills by using photography to convey mood, movement, or meaning, helping students articulate a personal response to sculptural works. All cameras are welcome, from your smartphone to DSLR. However, we recommend the camera you use has multiple lenses or a zoom, and ability to adjust exposure. Lenses in the range of 28mm to 200mm would be appropriate. No flash or tripod since we'll be in a museum. Questions can be directed to Marie Joabar at info@capitalphotographycenter.com. Class limit: 8-9 *** **THIS CLASS IS OFFERED THROUGH CAPITAL PHOTOGRAPHY CENTER** https://capitalphotographycenter.com/classes/class/2026-04-19-sculpting-photos

The Alexandria Brunch Club is a long running brunch event. We're a friendly bunch of people of different backgrounds, who enjoy a nice morning brunch and fun conversations. As has been the tradition, La Madeleine's in Old Town Alexandria is our place for brunching on a Sunday of every month. I find that a Sunday brunch is nice way to socialize and to just get myself out of the house. Afterward, Old Town, the Potomac and the myriad of parks are nice places for strolling after breakfast. BEST PARKING IN OLD TOWN Courthouse Square Parking lot 111 S Pitt St - Same side as La Madeliene, Two Doors Down Usually $1/hour Weekends and after 5pm, Weekdays For any questions and such feel free to message me. I am the main organizer. My best to all! Phil Matera

📚 Do you love reading, but wish you had a structure and a community to share your insights with? Join our small circle of curious minds (just 4 members per gathering) as we come together for an hour of focused reading—in the calm setting of a library or the cozy atmosphere of a café. Here’s how it works: First part: Quiet reading on your own—bring a book you’re exploring, whether it’s philosophy, history, psychology, literature, or anything meaningful to you. Second part: We regroup and each person shares key takeaways, insights, or questions sparked by their reading. This sparks a structured yet free-flowing conversation around ideas, perspectives, and personal reflections. Why join? Add structure to your reading habit. Discover new books, authors, and ideas through others’ choices. Build real connections by sharing and listening deeply. Socialize around something meaningful instead of small talk.

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.
