Did a thru last year, so I remember the main resupply points. I wrote down major resupply points for groceries/meals on a sheet of paper, along with the road, direction, and mileage. Saved 2.6oz, not worried about writing down shelter or water mileage, as they are noted or cross the AT, and I like to hike until I feel like stopping, not shelter to shelter.
Mainly being really into ultralight since I hurt my knee on the BMT. My pack was kinda light before, but since I tore some cartilage in my knee, I am having to get really serious about it. I am not going to quit hiking.
