I really do want to thank everyone that has replied. It is alot of common sence but it is nice to talk to people that may have had success stalking. The termal thing is really something I guess I never thought much off so I did learn something along with many of the other tips. I will post on my sucess if that happens. I do have a passion for mules and the tough country I live in and always a blessing to be out in the badlands. I might be differant then most but getting an animal out of the back country no matter how hard it is can be some of the most rewarding time of the hunt.
