They had an added 17 miles to get to a SAT phone and then take the injured guy to the evac pick up site. This was a boy scout Northern Tier adventure. Since my grandson is a T1D, he has to have a parent along who can work as his medic and one of the Scout leaders. It's a 2 kids per adult kind of thing. The evacuated guy was actually their guide! They had to pick up another guide at the evac site as well.thats a long one....ive got a canoe and two kayaks also, love the canoe for just relaxing and easy hauling. the kayaks are for island hopping on the coast ICW.... lots of fun. dont know about a 70 miler though...lol...
