If you're in Sioux Falls you'd better stay downtown. Besides the great restaurants, easy walks, free trolly to the actual Falls, and easy access to anything, the Sculpture Walk was fantastic. They are EVERYWHERE, and some are "interactive" (a metal couch that looked soft and comfy was something I had to try out for myself). Some modern, some mystical (the jumper with wings), some life size (greatest mama bear and cubs ever). This was a delightful surprise in downtown.
