The biggest morale killers are heavy rain and not seeing rams.
Fog is the worst for me, especially after you've committed the time (and pain) to get up into the mountains and then can't even glass. But if I were living out of a bivy, rain would be more of a problem.
Glassed 22 different rams this year, and couldn't make a single one legal. Still worth it to be able to watch them, and there should be some good hunting there in a few years.
