Sounds fun. I dont know if I can make it if its way up in northern Maine purely because of my budget.
one thing Ive learned is never underestimate a logging road. Winter can do a lot to the trails.
There is one around here that I've seen a stock chevy blazer attempt. He MIGHT have made it if it wasnt winter. 2 years later I doubt a truck on 35's could make it through some parts.
