been there done that got the T shirt, brother! The air's pretty thin for us flatlanders at 9600 feet, and a 40 degree slope!
The last time I was out there a guy in camp with me climbed up to "the top" on a bull he had bedded that morning. On his way uphill, the bull was headed down- right on top of them! He literally was in the trail the bull was using. As he was bugling his rear end off coming downhill like a freight train to the water that was 1000 feet below, my campmate loaded an arrow, drew, released, and two things happened: the arrow went UNDER the belly of the bull and stuck right next to his "business" in the dirt, and the shooter fell backwards and he and his bow rolled downhill about 75 feet, rear end over tea-kettle!!!
It was about a 370 bull. He still sends me emails about his nightmares, 6 years later.
