Hunting the mountains isn't rocket science and it doesn't need to be made out like it is.
If someone has never been in that back country, and at those altitudes, it can damn sure be deadly. When I lived in Rifle there were always reports of out-of-state hunters getting lost, some perishing from exposure due to an unexpected storm, etc.......
I wound up buying the US Armed Forces Survival Guide back then - always took it, even if just 4-wheeling for fun
Keeping an awareness of what is happening around you - weather-wise, terrain, etc. is important
