I just got back from a two-week stint on the AT and had a wonderful experience from someone providing "trail magic". I had hiked my longest day of the trip, in 93* heat. I was pretty beat when I showed up at Bear's Den Hostel. After a shower and changing into some clean clothes, I laid down on the bed to relax, when someone stuck their head into the women's dorm and announced, "It's dinner time!" Dinner? As it turned out, a thru-hiker named Cycle Hiker was staying there and his family had come in for a visit. They put on a huge feast for him and whoever was staying there that night. It consisted of steak, sausage, asparagus, green beans, mashed potatoes, fried potatoes, lemonade, mint tea, magic bars, Rice Krispie sandwiches, and three different kinds of cookies. There were mostly thru-hikers there and I believe all of them thoroughly enjoyed that meal. For me, as a shy person, it was a wonderful way for me to meet the other people staying there. In the morning, the family provided breakfast as well.
I had come prepared, with plenty of food. I didn't expect anything but a shower and a soft bed. But that stay at Bear's Den turned out to be one of the highlights of my trip.
I had two other TM experiences on that same trip. Both were near road crossings where I expected to see civilization anyway, and both provided a trash bag for the trash. I participated, and it didn't bother me in the least. Whether I will have a different opinion as a thru-hiker (in 2009) remains to be seen.
