I think the trail near Greenland is called T.R.A.I.L. U.P. Supposedly, it will beo over 1000 miles long when completed. It'll also go into pars of Wisconsin. And, it was supposed to open in August of 98.

 

Just rode the Norway Trail (the northern loop) in Dickinson County. I really liked the varied terrain which ranged from rocky outcroppings to blackmud swamps. The trail markings were screwed up at times so its handy to have a map of the trail and a GPS. Also, the trail shwed no signs of anything else but ATV's...that was cool.
