So me, my dad, my brother, and my sister's fiance are going to hike a section of the AT this fall/winter. I already have some gear, and I have recently bought some more, but I'm not sure if I have the proper equipment for the AT. Have any of you guys hiked the AT before? Is there anything special I will need to take? here's a list of my current gear. If any of you guys can think of anything extra I will need, let me know. We are going for about 7 days or so this time, and hope to hike from amicalola falls to somewhere just north of the GA-NC state line (90 miles).
