Should be warm up there (though you're probably used to that. 🙂 )
Downtown and the Capitol building is interesting. I went up there with my daughter on a field trip. We also visited some one of the Forts up there. You can get into the Capitol building, with a camera and walk around.
You can go watch your elected officials stand around, and turn into cardboard when you point a camera at them 🙂 .
One person in this shot appears to be working!
