We are actually staying in downtown Sioux Falls, the complex is just south of the city, I believe it is called Yankton Trail Park. Some have talked about driving to see the President's, it would make for a very long day trip.
I would be more apt to visit Captain Lou, we'll be about an hour north of Vermillion. I won't speak of the trip to aforementioned son, he already thinks he is a pool player. I keep trying to convince him that they do not make left handed pool sticks.
