We ended up riding out of Sunriver onto 97 toward Bachelor, but then hung a left to stay on S. Century Drive because the traffic seemed much lighter going that direction. We swung right to stay on S. Century Drive/Hwy 42 and went to the fish hatchery, where we turned around and went back to Sunriver. About 24 miles total of beautiful, sunny (snow on the sides of the road) riding. It was a very flat route, but a lovely way to spend the morning and get a little fresh air and exercise.
