This past weekend I had the pleasure of touring the Dupont Underground. The have some very cool exhibits and the people running the tours are fun and friendly. I highly recommend going if you have the time and you are able to get tickets. The are also in need of support. The space is huge and much of it does not have power because years ago people came in and pulled out much of the copper wiring and plumbing, so if you are able to support them in any way, I am sure they would appreciate it.
