Last year in Manitoba in the spring I thought I heard that a bow hunter had to beat a bear that was coming up his tree. I remember that because we were out hunting bears at the time and we packed some heat too along with the bow. You will need a bug suit because there will be a lot of bugs, after sitting one night in a full bug suit I still had 47 bites on me. Bear hunting is different then deer hunting, a deer can't climb up the tree and eat you
