I was charged by a large bull moose while grouse hunting in Minnesota. Since I was unwind and could not climb fast enough, or shoot him with birdshot, I quickly unzipped and pissed in the wind. That worked. I like to say I have the fasted zipper in the county. And maybe he felt less like a bull. Lol. But I knew the sudden smell would surprise him. He was chasing my hunting dog that had barked at him. The dog was running to me. I don't know if she was scared or saying, "hey dad, look what I am bringing to you".
Other things have happened, lost in a hige wilderness. Broke through ice, accidently shot at. Branch fell on me in windstorm. Truck stuck in remote area. My grandson says, that when things go wrong it is an adventure and grandpa has lots of those. Lol.
