I'm planning on thru hiking the AT starting March 2012. I've heard alot of people recommend mail drops as a way to resupply. I'm just looking for peoples opinons/recommendations as to how helpful or necessary they truely are. With the looming post office closures and time constraints of getting to post offices during busines hours, I'm tempted to say I'd rather just restock in town. Plus I'll know what and how much supplies I'll need at that time. How hard is it to find grocery stores close to the trail? Are the prices for food so high in trail towns that it outweighs shipping costs? Thanks!
