Following is a picture of a possible resupply plan. The basis of this was a post I found on wanderingthewild.com. I liked the philosophy of keeping as close to the trail as possible. You'll see out of about 35 stops, 20 are mail drops and the balance are local resupply. Most points are under one mile from the trail. The yellow highlight is no longer viable (but my son lives in Maryland). Others have been verified as viable through awol guide.
If interested I have this in a spreadsheet with mailing addresses. You can calculate your own days between towns based on your pace, etc. I'm happy to send anyone the spreadsheet.
