About a month ago when I turned 75 I started walking in rough country. They are measured 1 mile walks that because of the terrain are helping my new knee, and my balance. I started out taking about 8 breaks on that 1 mile walk but, I'm now at a point that the walk is at a good pace, and I don't have to take any breaks.
Now, back to the hunting.
Where I ranch (and walk) is all canyons and Caprock. There are mule deer, turkey, quail, an occasional rabbit, and calf killing coyotes. I pass on all the game but, the coyotes need to pay attention. I've always got a handgun, and sometimes a rifle. Most of what I shoot are rattlers.
Handgun hunting used to be one of my pastimes and I enjoyed it. Congrats on your obvious success.
