Went and did 30 miles on the Oak Creek bike trail with an amigo from MO...and then got the whacko idea to explore some MMR (Min Maintenance "Roads")....seen peeking over the hillock. No cars, only one marathon trainer. Bright, sunny, and nice.
5-15% MMR on dirt/mud rutted farm roads. Disc brakes needed on the way down....30-30 gearing needed coming back up.
