The absolute best magic I received was just into Va. Somehow I lost the little "key ring" and the peg that goes on the corner of my tent, into the pole. Happened to stumble across this as I was setting up my tent the night before and it was 3-4 days to the next small town (probably didn't even have a hardware store there). Stopped short to stay the night in a shelter and low an behold sitting in the corner of the shelter were 2 key rings and 1 peg that I needed to set up my tent. Coincidence? It wasn't mine, it was a lot smaller, but it's still on my tent to this day. To me, THAT was trail magic. But that's just one instance I endured.
Now I'm not one to turn down a cold one (soda or ?) but in my case, there seemed to be a lot more on the Southern end than up North. But heading North, there are a lot more "deli's" and such so maybe that's why. I don't know, just rambling but if it's there I'll partake and have a good conversation but to contradict myself a little bit, I think there's too much magic (feeds) on the trail. There were a few times on the Southern end (more often than not) where I just restocked, headed out, then ran into someone cooking up burgers. More North, I think the only magic I truly remember was TOG (The Omelet Guy).
