I found some old threads on this, and was hoping to draw some more
current discussion on it, as I'm interested in doing a little urban
exploration in DC. I'm particularly interested in bomb shelters and
transit tunnels, but I'm wary of exploring anyplace that might be in
use or inhabited, in this post-9/11 world of heightened security.
Does anybody have an experience specific to the city? How about tips
on where to start my expedition if not?
