But the best part of the park has got to be its legacy: From 1891 to 1990, it held a boarding school for Native American kids (hence the name), the main buildings of which are still on site today. While the buildings are waiting for restoration funds to turn them into a Native American cultural center and museum, the city has done an excellent job putting up historical information for people who are interested. Ambling from the covered bridge to the old buildings, you'll get a good sense of what life was like in the school just by reading the placards. Think of it as a free museum -- that just happens to have swings, too.
