Lehigh is a cool little town deep in the Des Moines River Valley. My two younger brothers and I did a Ft. Dodge Iowa sponsered ride around that area twice a few years ago. Camped in Dolliver State Park and rode through towns like Coalville and Duncombe. Killer hills in Dolliver and Lehigh. We need a local to chime in here. I am curious if the Karras Loop will go through Dolliver State Park.
