Al have you ever taken your bike on the Preston to Harmony trail in Minnesota? Its near that region. Thinking about doing it when I come up to Decorah this weekend.
When I was a kid. Haven't gotten around to it this year.
Been meaning to do that stretch though. There's a place in Harmony with good beer selection and solid bar food, and I want to start in Preston, ride uphill to Harmony, have a few cold ones, and then bomb back down the hills to Preston. Its more challenging than the rest of the Root River trail for sure, and closer to Decorah (if you start in Harmony and go downhill first).
