This is a very short ride and can be added to many of the other routes. Run this at least ones a month just because it has so many turns in 10 miles. Add it to the cumberlund route or Green water run if you are anywhere around Auburn Wa.
I grew up on this road. No, really! My parents lived up the hill from Flaming Geyser State Park. It's a pleasant road with nice turns, and the park is a nice place to stop and visit. This road helped me develop my love of twisty roads. It's a nice bucolic ride if you're in the area.
On our way to the monthly Washington state Moto Guzzi meet ups first Saturday of every month. They're all a hoot to ride with and very good.
