I hunt alone all the time. All my friends and hunting partners work, and I am retired. I go out alone every week or so for two or three days at a time. Yes I am cautious, one mistake and I am a gonner. Preditors are not my major worry, Yes I've had a few close calls with Grizzlies and Wolves, even a Couger in New Mexico while hunting Turkey. The real danger for me is the environment. Mother Nature is not very forgiving. A fall through the ice at 60 below can be the last thing you ever do.
A slip while skinning an animal can be disasterous. Simply wiping your face with the back of your hand while skinning a Beaver, then licking your lips can get you killed. You have the bacteria from the water the Beaver was in on your hands. You wipe your face with the back of your hand and transfer the bacteria to your lips. Then you lick your lips later without thinking much about it. Then suddenly the next day you are totally incopasitated with severe cramps, then the diarreah, then you start throwing up. Within three to four hours you are so dehydrated and weak you can not get up, or do anything. You can not tend to the fire in the stove and the cabin starts getting cold. You pass out from weakness, and the cold takes over, you never wake up. Another victum of Gardia, otherwise known as Beaver Feaver, a deadly bacteria. It comes from the feces left by the Beaver in the pond they live in.
