I have been seeing a lot of speculating in this sub about whether certain addresses may be "possibly" connected through the underground tunnels throughout the D.C. area. So I tried to overlay a map of what D.C. looks like today, and a map of the underground tunnels/streams that run underneath the city, using Baist's Real Estate Atlas from 1909.

Here's the map. There are two images on the page, one with the google maps overlays, one without. I tried to connect the dots between a few places of interest from this sub. Comet Ping Pong, Pegasus museum, and 4082 Chesapeake St. NW. I tried the best I could to stitch the google maps images together and it is mostly correct, but the google maps screenshots got a bit inaccurate towards the bottom center of the map. If anyone wants to help me correct that, please do.

Some interesting connections... I found that Comet Ping Pong is directly connected to Murch Elementary School, and another adjoining tunnel reaches close to Deal Middle School, which is coincidentally right by 4082 Chesapeake. There are also a few other tunnels connecting to Deal Middle School which are loosely connected to CPP from another vein. Also, CPP connects directly to St. John's College High school with multiple tunnels. ALSO, theres a connection between CPP and the Episcopal Center for Children.

However, I wanted to make the connection between Comet Ping Pong and Pegasus. There isn't really a direct tunnel leading from CPP to Pegasus. However, you could follow the tunnel, exit, and re-enter a tunnel nearby, which MAY lead to Pegasus. One of the tunnels cuts off just before reaching the map's logo and key, so it's possible that it could continue down to reach the Pegasus building. I wasn't able to find the plates from the atlas that lie just south of the map shown here. Either I'm totally missing something, or they purposefully don't want people to know where underground tunnels lie near the White House, which is understandable. If anyone can find the missing pieces of this map, I'd love to see them add to this one.

Anyway, I've been looking at this map for a couple of days, and I'm just really burnt out on it. I want to pass it off to anyone who wants help me fill in the blanks.

If anyone wants the illustrator file for the map, pm me.
