Spent the whole day crossing South Dakota and what a great day. A wonderful ride for the most part with fantastic roads (most straight as an arrow but smooth). Again I tried to stay on secondary roads some of which were flooded and required detours. As I neared Rapid City I realized gas may be a problem and I was riding across a large reservation with little population. I found Enblee, a small community that had gas and not much more. A large storm was brewing to the west and I was headed right into it. Chickened out and turned around but I'm glad I did. It was a doozy.
