haha... sounds like me. sub 1k feet for me.... of my 15 roosies, i don't think more than 2 were above 500ft.... possibly none.About 300' until a few years ago haha.
12k ft is impressive, living at 10ft I would be sucking air for sure
I get it and much of my elk hunting is a similar approach, but it’s way hard, you’re exposed to brutal winds, you stick out like a sore thumb and they can see you from a 1/2 a way.
