I am hiking approximately 50 miles along the TN and NC border. There are many guide books and maps available. I want to know what is necessary/good to buy. I have found the below options, so I wanted to reach out for any insight before buying. Thanks.
1. Appalachian Trail Thru-Hikers' Companion *do I need to buy a separate map?
2. The A.T. Guide (David Miller) *do I need to buy a separate map?
3. ATC Guide to Tennesse-North Carolina, 14th Edition (comes with maps)
