I like the idea of this adventure race, but I'm not sure a traditional cat would work. Assuming, you can get around the 40 mile portage, and the 100 mile upstream issue, how do you manage the river rapids? And what about restocking? Or do you pack for 20 days? How about sleeping/camping for 20 days, do you just come ashore and camp? Sleep on the boat? What have the past racers done?
