Good luck to you and your son on his hunt presmyk. I really look forward to hearing about it. The story Smith2260 told has happened to me a couple times. 400 yards across a canyon was my last cow. I didn't get to see her again until my brothers got her back to the truck for me many long hours later.
The ranch doesn't give a discount for CHAMP hunters but they do allow us to use atv on the ranch.
