Developed in the mid-19th century as one of the District’s first suburbs, Anacostia and its residents played a key role in shaping the city we know today. A walking tour led by historian and author John Muller traces its history and significance with a focus on the man that came to be known as the “Lion of Anacostia,” Frederick Douglass, who lived in the neighborhood from 1877 until his death in 1895. Blending historic research and contemporary neighborhood affairs and news, our guide will lead the group on a walk through time, exploring one of Washington City's most misunderstood and sacred communities. Stories of presidents, local personalities, famed resident Frederick Douglass, 19th-century architecture and neighborhood folklore will be woven throughout. Questions and photography are encouraged throughout the walking tour! *** **John Muller, author of Frederick Douglass in Washington, D.C.: The Lion of Anacostia (2012)** and Mark Twain in Washington, D.C.: The Adventures of a Capital Correspondent (2013), has presented widely throughout the DC-Baltimore metropolitan area at venues including the Library of Congress, Enoch Pratt Library, DC Public Library, Frederick Douglass National Historic Site and local universities. Muller is a frequent guest on Washington, D.C. radio stations and has been cited by the Washington Post, Washington City Paper, Star Democrat, Salisbury Independent and other publications for his local history research and subject matter expertise. He has been featured on C-SPAN’s BookTV and C-SPAN’s American History TV, broadcast airwaves of NBC4 (Washington), WDVM (Hagerstown) and radio stations WPFW (DC), WAMU (DC), WYPR (Baltimore), WEAA (Baltimore), Delmarva Public Radio (Eastern Shore) and West Virginia Public Broadcasting.

In previous years, the rangers said they try to get to the park and open the gate by 7:45 AM. From the website: [https://www.nps.gov/keaq/index.htm](https://www.nps.gov/keaq/index.htm) Waterlilies are bountiful all over the park! Our volunteers moved the tropical lilies from the hothouses to the display ponds, and they are vibrant. Bird enthusiasts have been enjoying watching the 3 young fledgling red-shouldered hawks, nesting orchard orioles, and kingbirds. Turtles have been laying eggs, and tadpoles and frogs are abundant in the ponds. Every year, we visit Kenilworth Aquatic Gardens on July 4th. The lotus flowers start blooming in early June and will be plentiful by the end of the month. The best time to visit is in the morning, as the temperatures are cooler and the flowers close up in the heat of the day, usually around 1:30 pm. I know it is outside of the Virginia Beltway, but it is not far. It is a very unique place in Washington, DC. I will be there in my grey pickup and rain or shine (hopefully shine)! Bring: Tripod Comfortable shoes Water Fully charged batteries Empty memory cards Rain poncho and plastic bags for the camera and lens in case of rain. Share only your very best, most interesting shots after the field trip, and keep it down to between 5 and 10 photos. Park Facts Entrance Fee: Free Allow Dogs with lease: No Bathroom: Restroom in the Visitor Center Address: 1550 Anacostia Ave, NE, Washington D.C. 20019 Lat, Long: 38.913003, -76.940142 - Parking Lot Plus Code: W375+6W Washington, District of Columbia Website: https://www.nps.gov/keaq/index.htm I generally schedule this meetup on the Fourth of July, as I would have the day off. They are open on July 4th, but one year we waited until 9:00 AM until a ranger showed up to unlock the gate, and it wasn’t a holiday. I also want to mention security, as in the past, a photographer in my group was at the gardens and saw someone’s car being broken into in the parking lot. From the parking lot, walk towards the gardens down the path. I usually stay to the left and head into the lotus fields. Please be careful, as there are just dirt paths between the fields, and if there has been a lot of rain, there can be ruts, and I almost twisted my ankle. You actually need a fairly long lens, as the lotus flowers are tall and can be some distance away. A wide angle is only good for some overall shots, and a good-sized macro works as well. Another thing folks do not realize is that the flowers do bloom into September, but have many full blooms. This is one park where you do not have to worry about mosquitoes, as they are eaten by pond beetles, dragonflies, and damselfly larvae, and also by frogs and birds. There is a boardwalk at the back of the flower fields that goes out to a marsh area. I have seen many types of birds and dragonflies in that area. Being there makes it hard to believe that you are in Washington, DC. On the way out, allow some time to check out the small ponds with different lotus and lilies that also attract frogs and dragonflies. Why you will not see any mosquitoes in the park: https://www.nps.gov/keaq/learn/nature/insects.htm By sending in an RSVP and joining this meetup event hosted by the Virginia Beltway Photography Meetup, I am also agreeing to the terms of the following release and waiver of liability, which shall be binding on my heirs, executors, administrators, successors, and assigns.

It's going to be hot! Let's stay inside and meet at Blue Bottle Cafe at Union Station. Between the architecture and the people, we will have plenty of inspiration. There is also an ongoing exhibit of cars from Ford for the [Ford USA 250 exhibition](https://fordauthority.com/2026/07/ford-usa-250-celebration-features-some-amazing-vehicles/), which might inspire your drawings!

There are toilets at Great Falls and Fletchers' Boathouse. We will e-bike from Glen Echo Park in Maryland to the majestic Great Falls. We will be biking on the Capital Crescent Trail, the C&O Canal pathway, and McArthur Blvd with separate biking lanes. This tour captures the essence of adventure and natural beauty. We will be meandering alongside the serene Potomac River and the C&O Canal, offering E-bike Lovers an unparalleled opportunity to immerse themselves in the lush landscapes that define this region. Glen Echo Park, with its rich tapestry of cultural and artistic heritage, serves as the perfect prologue to a journey that gradually unfolds into the wild, untamed beauty of the Great Falls. The route is just over 26 miles on gravel and asphalt. The gravel is compact. If you don't like the gravel on the C&O Canal pathway, this is not your route. Entrance to the Great Falls National Park is for free as we enter from the C&O Canal. We park at the large parking lot off Oxford Street, NOT at the smaller lot at McArthur Blvd. Please bring snacks, lunch and plenty of water.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
