You guys got it all wrong! I pick my hunting spots purposely in the "hot" squirrel areas. Deer are long time "blood" enemies of squirrels. The deer eat the squirrels winter stashes of nuts when the long cold winters get rough. When I hear the squirrels barking I know the deer are moving and get ready...The squirrels either dont see me or Dont consider me too much of a threat because they dont bark at me...I luv squirrels
