10 miles is actually a pretty short backpacking trail. But you gotta start small and work your way up, right? Cutting a 10 mile hike into two days should be doable for most everyone. The main challenge (i.e. the good part) is the fact that only one night also allows us to travel light and cook over an open fire. No big coolers here, if it doesn't fit in a backpack, it's not coming along.
So, I know no everyone will want to do this because of the lack of luxury we're used to, but that's why it's a challenge. I'm just offering this as a chance to hang out as manly men and find out what we're made of. Not doing this anytime soon, so don't worry. I'm shooting for late May.
