Many historic American factories are open to the public. Here are the ones worth the trip.
There’s probably no escaping taking the kids to an amusement park this summer—sweltering in long lines and paying for overpriced junk food. But when that torment is over, take them to a different kind of theme park, one you’ll both enjoy: an American factory. You’ll see how baseball gloves are made. Or how they print the posters for your favorite concert. Or how a guy at Harley-Davidson takes every bike up to 77 mph on what looks a lot like an automotive treadmill. Sometimes you’ll even get candy. And unlike at Six Flags, admission is often free.
