These are some determined bears! But alas, no luck!
This totally reminded me of a bit that Kidd Kraddick did that cracks me up every time I hear it! Check out the second video, further down!
Kidd interviewed this guy and played his song "Bears" many years back. It was radio magic! I wish I could find that bit online. But we'll have to settle for just the song.
"Bears Never give up. They just want to make a hunt."
...Except for the bears above. They did, indeed, give up. Sorry Sergio!
