Howdy ,Hunting in West Tx. can be Hot or Cold! I have seen 50 deg. swing in just hrs. As far as my leather boots I use hightops for the cactus more than the snakes ,even though they, call em snake boots. I coat them with snowseal two times a yr. Keeps em waterproff and they dont crack in the hot&dry. And it can get dry in the desert Amigo.I think Cliff hit the nail on the head with the Wool. I use Wool shirts.With a Buckskin coat over the wool shirt a felt hat and some Mohair socks made here in the Hill Country region I am ready for some pretty cold weather.I'm kinda like Pony Express about the knife ,mine is a Old Timer Trapper my Dad gave me 30 somthing yr. ago. Cant tell you how many animals it has skinned, or meat it has made. Guess in the hundredes. If that knife is not in my pocket I walk funny .Good Hunting, here is a pic. of yours truly in front of the 5C Hedquarters a couple wk. ago..........Dusty.
