Photograph Kenilworth Aquatic Gardens July 4th
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.

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 wasnโt a holiday. I also want to mention security, as in the past, a photographer in my group was at the gardens and saw someoneโs 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:

**Nothing better than having a few drinks at your favorite poorly air conditioned dive bar and getting hot and sweaty on the dance floor with friends and strange-ones.**
**KatBootyJuice is led by the enigmatic funkmeister, Jimmy Gold, and his five string bass with his groove masters playing funky favorites from the 70s to the 90s.**
**VFW Post 350 (Hellโs Bottom) is a fav hangout with cheap drinks, friendly irregulars, live music 6 nights a week, and a decent dance floor. The Henry Sisters food truck has a tasty menu of offerings. Thereโs a parking lot or nearby street parking.**

Pathfinder Society Scenario #7-16: A Star's Journey
# Pathfinder Society Scenario #7-16: A Star's Journey
A Pathfinder Society adventure for 1st-2nd level characters, playable in 2-3 hours.
During the exploration of an ancient Jistkan ruin in Katapesh, the automaton Star goes missing, leaving their archeologist companions worried for their safety. The head archeologist calls upon the Pathfinder Society for assistance, but warns the agents that arrive that the ruin is filled with dangerous creatures and traps and that they should be careful while exploring. A strange frozen automaton meets the Pathfinders on each floor, slowly pointing the way deeper and deeper into the ruin. Will they find Star? Or does the automaton have more malicious motives?

The Completely Series
These meetings will be a building block approach to learning photographic mastery over three disciplines:
Completely Mechanical (CM) - A 13-week series
Completely Exposed (CE) - A 26-week series
Completely Composed (CC) - A 52-week series
All three series will run concurrently and will dovetail as follows:
Q3/26 - CM (Iter 1), CE (Iter 1, Pt 1), CC (Iter 1, Pt1)
Q4/26 - CM (Iter 2), CE (Iter 1, Pt 2), CC (Iter 1, Pt2)
Q1/27 - CM (Iter 3), CE (Iter 2, Pt 1), CC (Iter 1, Pt3)
Q2/27 - CM (Iter 4), CE (Iter 2, Pt 2), CC (Iter 1, Pt4)
That's likely confusing, but essentially, CM offered 4 times in that period, CE offered 2 times, and CC offered 1 time.
**TO BE CLEAR - THERE IS NO CHARGE FOR THESE CLASSES.**
This is an aggressive series, with presentations, homework, group shoots to be added in, likely at LEAST twice a month, image critiques, and an expectation that you are willing to put in the work to elevate your photography significantly. Open to all levels and all equipment levels. Don't let hesitation about your skillset and/or gear keep you from a one-time opportunity.
The group will meet every Tuesday, with periodic exceptions, and we will try to keep as close as possible to the original plan. Obviously, more data is coming and will be published as this is further developed, but now is the time to decide if you want to be a part of this.
IxDA Chat n Pancakes
You can sleep in on the Semiquincentennial (observed), weโre shifting to the following Friday.
But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why Iโd even want to.
Thanks to the team at Nationwide of supporting the group.
Monthly General Meeting
This will be our regular monthly meeting, with a new topic picked each month. Topics to be determined and posted soon.
Columbus Code & Coffee 88 @ Improving
Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you!
