That is a creepy thought everytime we are out hunting. We haven't had dogs in the past so we do all the retrieving ourselves..I am always checking my next step but you never know. That had to be a bad feeling when you started going down.
I know I was walking in a river once when we were swimming and all of a sudden my leg sank down up to the goods. I tried to walk around and find the hole again (the water was only ankle deep to start with) because my friend didn't believe me. That was a weird experience
