My wife and I spectated at few stages of the USAPC two years ago. The best was the start of the individual TT as it's strung out over a long period of time so you can get close to the action and riders and see a lot of activity in the pits. The finish depends on the type of stage but it's over-with pretty quickly, with a bunch finish being the most exciting, I think. Usually all the vendor booths and exhibits are at the finish so that's cool to check out, but they're basically the same each stage. Staying out along a good climb is kind of nice, but it's got to be really steep because those guys go amazingly fast up hills. We stayed in Denver and drove to the starts and finishes.
