Pretty sure the OP isn't 80.
Obviously you've never had the joy of getting up at 4:00 am, hiking a mile or more to an early morning spot on a rim before dawn and then at first light, some [bleep] from out of state rolls up on the other side on his noisy ATV, oblivious to the fact that he just pushed all the elk out of the drainage.
I have.
I have too. The last time it was a guy from New York and I gave him a earful.
I have too. The guy was from Big Sandy, MT.
The day before I had hiked up to the head of a drainage, dropped into another drainage and bivouacked. Next day had elk fixing to run over me and I stopped one.
You have to use those ATV's to your advantage.
