The Appalachian Trail has been done kilted before, but never in a Bear Kilt. The kilt of course isn't as popular as shorts on the Trail, but this year I saw more people wearing the Mountain Hardwear "kilt" (it's really more like a sarong, but it is made for men), and a few people wearing Sport Kilts. One other person finished before I did in a Sport Kilt. However, I know that most people who did wear kilts also brought along long trousers or long underwear for cold weather, and shorts for hanging around camp after hiking. I did neither. Toward the end of my hike I did get a pair of boxer shorts to wear while I slept, but only because it was too hot to sleep in my sleeping bag, and I didn't figure other people wanted to see me naked.
In any case, it is an accomplishment. This year, about 1,300 people started, and only around 20% will finish. I count myself lucky to be in that 20%.
