Dyke Marsh Wildlife Preserve is known as a top regional birding spot; over **300 species** have been recorded here, including nesting bald eagles and ospreys.
Bring your longest telephoto lens and binoculars. I can help you with camera settings so you can capture sharper images of both perched birds and birds in flight.
It is thrilling to capture the amazing orange and red colors that are only available at that time in the morning.
Share only your very best, most interesting shots after the field trip, and keep it down to between 5 and 10 photos.
Bring water, comfortable shoes, a tripod, fully charged batteries, and empty memory cards...

DC Metro Crafts Happy Birthday meetup @ Shakespeare Library Cafe in SE
It's my birthday! Let's craft. We'll be meeting at Quill and Crumbs at the Shakespeare Folger Library in SE.
The Shakespeare Folger Library is about 3 blocks from the Capitol South metro. Head up First as you get out of the station, pass the Library of Congress and the Capitol, turn right on East Capitol, and the Folger is on the right. The entrance is around the side, not through the front of the building. Head upstairs to the cafe and we'll be at the tables at the back.
Bring your own cross stitch, knitting, crochet, or other portable craft.
A Poetry Workshop
Hey Poetry Lovers!
This group is on a roll. Here’s the gist:
We meet at the **Capital One Café in Chinatown** from **12pm - 2pm** every other week.
For enrichment, we start by reading and reflecting on a **“published poem”**, suggested by someone in the group. No advance preparation is necessary. But feel free to check out some of the poems we’ve read [here](https://docs.google.com/spreadsheets/d/e/2PACX-1vSyE_wCLQCPHRrKmN5F9tOIeeRQUZESxjRXGVBoCF2uU8Gm0_d0uECiCBCQXEy6ksxfsBOhtRIOpW3T/pubhtml?gid=0&single=true&widget=true&headers=false%22%3E%3C/iframe%3E). Or submit suggestions for future meetings [here](https://docs.google.com/forms/d/e/1FAIpQLSexGc2Z2Kp6bZW0D3_hfJ7NUUkfNHf7TXX-43FglCeBd9EF2Q/viewform?usp=send_form).
Next, we **share our work and offer feedback**. Depending on attendance, everyone gets \~10 minutes to use as they like. (No need to share, though; you’re welcome to come even if you prefer just to listen.)
We maintain a **Discord server** to help share our work and communicate outside our bi-weekly meet-ups. If you haven’t used Discord before, take a moment to download it and create an account before arriving. When we meet you on Saturday, we will add you to our server, the “DC Poetry Workshop”, and can help you navigate the app if you have questions.
Finally, if you plan on sharing a poem, consider how you will do so. Some options include:
* Print 5-10 copies to distribute in person
* Take and share screenshots in the Discord chat.
* Copy the poem into a google doc, change sharing settings to “anyone with link”, and copy the google doc link into the Discord chat.
Most importantly, we’re excited to meet you!
Catch you on Saturday,

Socrates Café Rockville Meetup
Socrates Cafés are gatherings around the world where people from different backgrounds get together and exchange thoughtful ideas and experiences while embracing the Socratic Method; the idea that we learn more when we question, and question with others.
Although this may be considered a "philosophical" group, there are no rules as to what is discussed. Those attending decide upon the questions of the night. Usually, the topics revolve around social concerns, moral issues, and the first principles of things.
Prior to each meeting we vote online for the questions we will discuss. That way, we will have enough time to ruminate on them and have more in-depth conversations. If you RSVP to a meeting, you may post your question in the event comments section below. I'll send out a survey for voting a few days prior to the meetup. We discuss two questions each night. So you will get to cast two votes in the survey.
When we meet, we break into smaller groups of five to seven to discuss the top two vote-getters. Each group discusses one question for around 45-50 minutes, and we then take a short break. After reconvening, each group moves on to its second question.
Hope to see you there!

Join DC Polyam and OPEN at DC Pride 2026
🔗 Please RSVP to volunteer here: https://forms.gle/hRoBtPgMFPsyAjMZA
OPEN is joining DC Polyam in Washington D.C. — come find your people!
This wil be our second year returning to Capital Pride Fest! Join us in the parade and at the booth! Whether you're poly, relationship anarchist, open, or simply curious about what ethical non-monogamy looks like in real life — our booth is a welcoming, judgment-free spot to land.
Non-monogamy and queerness have always shared space — in our values, our chosen families, and our fight to love freely. OPEN exists at that intersection, and Pride is one of our favorite times to gather, connect, and celebrate how far we've come together.
For the OPEN contingent in the DC Pride parade this Saturday, we will meet up in the "staging area" on 15th street somewhere in the 2-block area BETWEEN Q & R STREETS. Please arrive there between 3:30 and 4:00pm.
Look for a brown Honda CRV with OPEN's "Normalize Non-monogamy" banner on the top.
Dupont Circle is the nearest metro but it's also a similar 6 block walk from U St, Farragut North and West stations.
PLEASE come ready to walk in heat about 2.5 miles total: good shoes, hat, sunscreen, sunglasses, water bottle, fanny pack or backpack. Arrive pre-hydrated! We will have some additional water and ice in the SUV for refills.
Last year we had about 30 poly/ENM people for our parade contingent proudly flying the colors for Polyamory and Ethical Non-monogamy for all of the crowd along the parade route. Would LOVE to have more this year! Come out! Bring friends! And let's put non-monogamy prominently out there! This is HOW we actually start to make progress to "Normalize Non-monogamy" by physically showing up and showcasing the message and the cause! Let's do this.

Drunken Philosophy: Where Is Everybody? The Fermi Paradox and the Great Filter
Welcome to Drunken Philosophy, a casual, curious, social discussion club. Come grab a drink and a seat at The Oracle.
**Optional topic for this meetup: Where is everybody?**
In 1950 the physicist Enrico Fermi was talking about aliens over lunch and asked a question that still has not gone away: if the universe is so vast and so old, and even a fraction of those billions of stars have planets, where is everyone? By the numbers the galaxy should be crowded with civilizations. Instead we look up and hear silence. That gap between "they should be everywhere" and "we see no one" is the Fermi Paradox.
One of the most unsettling answers is the idea of a **Great Filter**: somewhere on the road from dead chemistry to a galaxy-spanning civilization, there is at least one step that is almost impossible to get past. Maybe the filter is behind us. Maybe life starting at all, or simple cells becoming complex, or intelligence ever evolving, is the freak accident, and we already cleared the hard part. Or maybe the filter is ahead of us, and advanced civilizations reliably wipe themselves out before they spread.
Here is the part that messes with people. If we ever found life somewhere else, even pond scum on Mars, most people would call it the greatest discovery in history. But it might be the worst possible news. It would mean life is common, the early steps are easy, and the hard step is still in front of us. So the eerie silence overhead might actually be the best sign we could ask for.
**Questions to wrestle with:**
* Is it better to be alone? Would you rather we find alien life and learn we are not special, or find nothing and quietly improve our odds of surviving?
* Where do you bet the filter sits, behind us or ahead of us, and why?
* If it is ahead of us, what is it? Nuclear war, climate collapse, AI, something we cannot even picture yet? And can we do anything about a filter we cannot see coming?
* Two principles pull opposite ways here. The principle of mediocrity (the Copernican principle, Sagan's "no privileged place in the universe") says we are ordinary, so what happened on Earth probably happened everywhere, which makes the silence scream louder. The anthropic principle says of course we find ourselves somewhere life was possible, since we could not observe anything else, so our being here may say almost nothing about how common life is. Which lens do you trust, and does the silence still demand an answer once you account for observer selection?
* And if we did confirm life out there and had to accept we are not special, what would that do to belief in a higher power, and would shedding (or keeping) that belief help or hurt our odds of pulling together as one species?
* Does any of this change how you live, or how humanity should be spending its time and money right now?
As always the prompt is optional. Come for the conversation, stay for the drinks, and bring your own questions.
