Actually some really cool trails for not being singletrack, some pretty decent
tech stuff, some decent hills, the cool iron soil of northern Wisconsin, and
you can ride to the highest point in Wisconsin. Very cool! I looked at a
map of cross country ski trails and snowmobile trails in the county that are
legal to mountainbike in the summer, and if memory serves there were well
over 100 miles. If that's your thing, then you may need to check northern
Wisconsin out.
In Montreal, if you are heading north on the highway (77) go right off the <br />highway until you can't anymore (about 2 blocks) and look for them.
