I've only had one sit and look up at me while talking to him trying to get him to leave he had me a little worried to what I' was gonna do if he climbed up but he finally walked off , a buddy of mine had one climb about half way up to him it was around 200-250 and was on the back side of the tree LOL. Funny now but he was scared I could hear him yelling it climbed down ate his apples and left he had his pistol so it would of been ok I guess never know , but I always told him and others don't use apples , pears no buck jam products nothing sweet smelling they will be there fast it's hard enough just to use corn for the youths with out bears coming in and ruining things
