Niagara Falls, Ontario (Canada): I've been to the falls before, but never took the chance to jump in (figuratively, of course) and check them out. The people in the past were too cool to do the touristy thing, but the people in the present were all about throwing on the blue trash bag, crowding on a cheesy boat and feeling the mist of the falls in your face. Now THAT'S what's really cool!
Here are some "I was there!" pics (thanks to Jim Kimball for his contribution):
