touche, Elder, AT Traveler, McPick! Whatever it takes for this old fart to stay on the trail, is all that I care about. Don't need to be a superstar to endure and maximize my enjoyment on the road. Preventing edema and blood pooling is a good plan to keep them puppies plodding along. Also the white socks let you see ticks easier. Lyme disease will quickly neutralize all these arguments!
