A friend and I rode from state rd mccct north of Baldwin to 72 +131 some years ago and it took about 4 hrs with breaks and beaver dam crossings, but that was in the spring. I rode with you ted and woodsy 2 years ago at sow after the main ride and from what I remember if your son is as fast as you maybe you can pull it off. Wish I could go and good luck! 1TRAK
