Serious looking slope, that! When do you think you'll be feeling good enough to tackle something like that again, Ben?
FWIW, 20yrs. ago I was 'packing about 70# into the interior of the Porcupine Mtns Wilderness, in the UP; right into the center of it. Got to camp and went out to forage firewood and 'had a significant coronary episode'. This was pretty much pre-cell phone days, so no com, spent another 3 days pacing myself and walked about 22mi. out. Best thing was living to tell about it, or brag; I was 39.
One never can tell when, and you can only be about just so prepared, so make sure youve made peace with all before you go in.
