A couple of hills

I went out on a terrific ride today.  I rode my Cannondale cross bike, which is a little on the heavy side, but an incredibly versatile bike.  I tried to find as many hills as I could between here and Willow Creek State Park.  I then took a little ride on the ridge, and dropped down Box Spring Road, or at least that is what a sign said.  From there I rode back towards Guerneville on Hwy. 116.  I couldn't pass up the chance to ride up over Duncan Road, which is all dirt.  I had planned on riding over Sweetwater, but thought it might be good to get back home instead.  Here is a map of the loop.
