Mora, for flying inside the US, I recommend checking out

Kossu, My, Zombie, Z's brother and Lart made a two week trip in march, checking out a bunch of aviation museums. They started from florida, drove to alabama, kentycky, ohio and finally washington dc. You might want to post on the virtualpilots news for tips.
