If you see a bear in your backyard - or ANYWHERE for that matter - let me tell you how NOT to scare it away. I know because wildlife rangers in Colorado already tried and it didn’t work. They blasted "Iron Man" from Black Sabbath, thinking (and hoping) it would annoy the bear so much it would just leave. NOPE! Must have been an Ozzy fan.
Yes, of course there's video:
My favorite part is when the ranger says “if he starts banging his head, we've got a problem.” YA THINK?!?
