RE: The one item you would not go without...
I started using the merino wool socks about three or four years ago. Now I will not wear any other type of sock while hunting. That wool is soooooo soft it is hard to believe that it is actually wool. No need for a liner sock any more to keep from iching. Definetly try them out this upcomong season. You won't be sorry. They hold up a lot better than the regular wool does too.
Believe it or not Wal-Mart has a really good selection of merino wool socks by Rocky, Woolrich and one endorsed Ducks Unlimited. They usually carry a light weight, medium weight and an expedition weight.
