Just don't look like one. He may think your mateable!
Long time ago, me and a buddy were in bear territory hunting dear., we were getting a little uneasy..... we were walking through high brush ( bears love to sleep and hide in it ) time to lock and load......next thing I know my buddy is jumping around ,just yelling and kicking up dirt, marking trees like a male dog........I say "hey man!, ..just what are you doing?".....
He says " Well , I'm not sure what time of year is bear mating season is,so if any bears are watching they will know I'm a man!"
