For those of you who have thru-hiked, done an extensive amount of hiking, or anything of the sort...I pose a question for any and all of you. If you could give just ONE piece of advice to someone about hiking, what would that singular piece of advice be?
I'm sure we could all talk for ages and argue about all types of things, but I'm curious as to what everyone would choose to throw in as their two cents about hiking, especially thru-hiking the AT.
