Today is our third night in South Dakota, the 13th state we've gone through on this trip. The past three days of riding were made much easier by very strong tailwinds, but today the winds shifted and we had to deal with some headwinds and crosswinds. We had a wonderful time on our day off in Rochester, Minnesota. Rochester Fest was going on while we were in the city, so we were able to enjoy some live country music and great street food. We also were given a wonderful tour of the Mayo Clinic's cancer center. South Dakota has been good to us so far, and I'm really looking forward to getting to Stephan tomorrow and staying on a Native American reservation. It should be a great experience, and I'm sure we will meet some fascinating people.
