I usually ride Black River Falls ( Jackson County) or Neillsville ( Clarke County ) trail systems. They are both 2-3 hours to get there but over 100 miles each and well worth it ( gas and food on the trails, etc). In 2 weeks I am going on a ride in Dunbar,WI ( North of Green Bay) and will give a report on how these trails are, never been there before. I am also going to Silver Lake Sand Dunes in MI Sept 28-30 with a bunch of Wisonsin Ice Racers and friends ( if interested in going, e-mail me).
