^ loads to see and do in Colorado. I wouldn’t mind living there some day.
Yellowstone National Park leaps to mind. Aside from that, I don’t really know; I’ve never been one for touristy crap. I guess you could go to Washington, DC and look at all the enormous white phallic symbols. Go to NYC and see where the towers stood (then get the fuck out, because NYC is a shithole). Go to New Orleans and make fun of people’s accents.
Disregarding the tourist shit: If you for some reason end up in Kirkland, WA, you could play Whirlyball, which is like lacrosse in bumper cars. Seattle, WA has the Pike Place Market, which is fun to peruse. The Experience Music Project is also in Seattle, and it’s pretty fuckin’ cool. In Portland, OR, there’s Powell’s City of Books, which is an independent bookstore that is two stories and covers an entire city block. I could spend days in there and never get bored.
