I don't think the majority of us where kilts. I do think that we are more free with our minds so maybe we are more open to the idea of running in a kilt. I would love to have one for running. The fresh air, the lack of a seem to chafe between the cojones and the thigh, sounds so great. One day when money is not tight I will buy a blue one like Jonny's.
Every year, I section hike a part of the Appalachian Trail for a couple weeks and usually run into a few thru-hikers wearing kilts. Kilts are the next step after going Commando.
