St. Louis isn't a huge city, but if we're counting per capita, it boasts more museums and libraries than any city on our list (and it beats New York and Washington, D.C., by a factor of 25). That's good news for folks looking to have a good time on a budget. Admission to top attractions, such as the city zoo and science center, is free. Citygarden, a $30-million, mixed-use sculpture park in downtown St. Louis, promises great gardening, art and picnics year-round. And if you do feel the need to spend some hard-earned cash -- at a Cardinals game or in the downtown shopping district, perhaps -- your money will go further here. While St. Louis residents earn roughly the same amount as average Americans, their living costs fall nearly 9% below the norm.
