PM sent. Be aware that the nothern loop is a long way between fuel stops...unless you top off in Big Bay. You will need at least 120 mile range (when leaving from Marquette). The short green track follows the snowmobile trail from Forestville out to Co Rd 510. This section is short, but it can be very steep/rocky/muddy. I was thru it this spring and 4X4's really had it torn up. Do you have a gps?
