I thru-hiked the Appalachian Trail from Maine to Georgia. Started with a 70lb pack, zero backpacking experience and 70 lbs overweight. Finished with a 21 lb. pack and skinny as a rail. AMA!
EDIT: Need to hop off for an hr. or so, will be back and I PROMISE to answer nearly everything!
EDIT 2: I did not expect this kind of response. But I will continue to answer. You guys are great.
EDIT 3: OK, I am going to post a long reply to those asking for more general advice. After that, I'll do a few more answers to direct questions, then try to pick it up tomorrow. Thanks everyone!
LAST EDIT: Thanks, all -- so much! Was great fun. If any of y'all have other questions about the AT (or Cairo), feel free to DM. Thanks again!
