Sioux Falls is either in the worst place or the best place. For someone who is flying into the Black Hills, it is not in a very good place. A person has to get there by driving across the State of South Dakota. That is a long boring six hour drive. However, for someone crossing the country on I-90 it is in a perfect place. It gives a nice break. Unfortunately, I was only able to visit Falls Park. Falls Park is a very easy and close find to I-90. I did not get to spend a lot of time; however, I was able to stop off and have picnic.
