Hello! This is my first real post (besides a quick into in the rookie forum) and I'm still working things out, so please bear with me if things look a little cloogy. Some of the pics are sideways-- ignore that as much as you can (couldn't get the to go right). Please forgive my total n00b-ness! And feel free to move this post to the rookie forum if you think it belongs there.
I've been draining near my house in the DC area a couple times, and I wanted to share some pictures from my most recent expedition. The drain seemed pretty large, at least we were in there for 2.5 hours and still didn't seem to be even halfway through.
(1)It was double-tunnel drain that continued for a while before spilling into an extremely big room underground. (I know this picture has an entrance in it, but it could really be anywhere...)
There were five or six different person-sized pipes that spilled into this room, so I guess the drain probably services a LOT of the surrounding area. (I didn't include a picture here bc there were no even marginally legible ones. It was the best I could do using a cellphone cam flash and a mini maglite...)
(2)I climbed up some rungs here and peeked through a hole in the manhole cover. I may have been wrong, but I think we were right under the police station
There was still a lot more to explore, but at this point there had reached a 30% chance of rain, so we decided to gtfo.
(3)We exited through the 2nd of the double tunnels. I squeezed into a little crawl-tunnel on the way back (there are some benefits of being 5 ft 4 and 130 lbs, I've discovered), and looked through a grate to try to figure out where we were. A pity my partner didn't get a picture of my ass wriggling up the pipe, that probably would have looked pretty funny.
(4)A good walk back later, we popped out of the outfall, slightly soaked but still very much alive. I hope to return to this drain soon and investigate the rest of it.
