You're lucky its only your feeders. We have a couple here in our village which is separated by a highway. On one side is a small bear (150-200) that likes to roam the streets at night. But on the other side there is one that is estimated 450-600 lb that ripped open the guy's garage door - actually ripped it apart, grabbed the garbage can and drug it 50 yards into the woods. My cousin almost hit him with his Ford Escape two nights ago.
