, Welcome to the board! Cool name, BTW.
Anyhow, considering where you're located, go to Goggle and punch in, <The-name-of-your're-hometown
"federal building">. In your case, the article of the No. 1 hit, seems like it would be a very interesting place to visit. (Since you didn't put you're location in your profile, I've left that out here, in this conversation, as well.)
Inertesting federal facitilies to visit: The nearest Sercret Service, BATF, FBI, CIA, or Customs office, Veterans Hospital
, or etc. Other places I know of, that may not be tapped, but can be visited... the Command Post of a nearby military base/post/fort, the nearest National Weather Service office, Air Traffic Control tower. And here's a good one for an evening trip... the nearest U.S. Postal Service 'Processing and Distribution Center'--rows and rows of machines processing tens-of-thousands of pieces of mail per hour.
