Bye-bye South Dakota

We stayed at a state park in Gillette, Wyoming and started early for a long drive east. We loved the Black Hills of S Dakota, especially Spearfish. Drove through the Badlands, but was disappointed in Devils Tower. I thought it would be impressive like it is in the movie. I guess you have to be from one of those flat states to be in awe. We stopped at Wall Drug for 5 cent coffee. The coffee wasn't bad! We drove 400 miles across the state and never had had phone coverage- no trees, no mountains- why not coverage AT&T? Saw corn fields everywhere and then a nice change - sunflowers! They were beautiful.
