I thru-hiked the AT flip-flop style, 2009, out of Waynesboro VA. I’ve been doin’ the vegan thing for about 5 years.

Lesson learned on ‘flop’ : Maildrops are your friend. So is talking to other experienced veg*n hikers to know where the good re-supplies are.
The main bummer for me was having to turn down so many pancake breakfasts from trail angels. One of the first things I did when I got home was make a [vegan] chocolate chip pancake breffast,
Two parting words of advice : powdered soymilk .
