HEy Roach....
There are a bunch of us who ride regularily at Tyrol BAsin just west of Madsion. In fact we have at least 20 of us that race in an adult race league on Monday nights. Drop me an -mail if you are coming to the area, or if you would be interested in racing with us on Mondays.
Granite Peak(formerly Rib Mtn) has great terrain. They still don't have much for lighting so most of it is closed at night, but I think they are supposed to add more this year. Its a great place to go if you don't want to spend all the time to get to the UP. :D
