SIOUX FALLS, SD.  Last night we had a hard rain which brought cooler temperatures today (60s) along with strong wind turbulence on the highway.  This is the first time on this trip that I have had to deal with side winds.  Thus, I drove no faster than 60 mph, constantly steering against the wind.  And when we entered South Dakota, the speed limit on I-90 was 80 mph, which is common out west, but it really made me look like a snail.  The traffic was not heavy, so it was not a bad drive, just slow. 

We are camped for the night in the middle of a city, so no nature trails, no pool, etc.  Pretty Spartan RV park, but pricy none the less.
