We made a stop at Governor Dodge State Park near Dodgeville WI in the southwestern part of the state. Nice park, very nice park, but not much for MTB'ing. It is connected to a nice rail trail called Military Ridge, but it was mostly mountain biking we were after on this little journey.
They have about 9 miles of MTB trail, but some of it looked like this. It was wet, and I normally would not ride a wet trail, but in this instance I figured some use is better then none.
The above pic is some more of the trail. These trails are shared with horseback riders. In all fairness, some of the trail was very nice, but two track.
