27 July 2018 Custer SD to Sioux Falls SD

We left Custer and drove down to Rapid City where we picked up I-90 East to Sioux Falls.  There is NOTHING between Sioux Falls and Rapid City. The land is flat with miles and miles of either prairie grass or massive fields of corn. We stayed in Sioux Falls at the KOA ($64 a night). The KOA has gravel roads and gravel sites which were not very level. But water pressure is good, WiFi was great, no cable, but our pull through had a lot of room for our fiver. They had a nice dog run, putt putt course and a small pool. The weather for the drive was cool and windy (we averaged 8.4 MPH).
