Quit telling people that you’ve been to Indianapolis, if the airport counts. It doesn’t. For those with time to kill, we’ve got more than 50 things for you to do in half a dozen U.S. cities, and all are within an hour from the local airport.

MAYBE YOU’RE SITTING in an airport in a city that is not your final destination. Or perhaps you’ve landed early and your business meeting isn’t set to start for another few hours. Sure, you could sit in the terminal and stare at your BlackBerry, channel surf in your hotel room, or buy another paperback to pass the time. Or you could explore.

If you’re in Boston or Chicago, you probably know what to do; there’s unlimited entertainment close at hand in such major metropolises. But when you find yourself in Salt Lake City, do you know where to go? What about in Indianapolis? Or in San Antonio? We've found attractions to satisfy just about every interest -- and each is just a quick jaunt from the airport -- in six midsize cities that warrant more than just a flyover.
