Right off the bat, this does not look like a very good situation for neither man nor beast.  This grizzly is very territorial and intends to assert his rights to the guy on the dancing horse.  It's noisy and confusing.  If I had to pick, which I wouldn't want to, but if I had to - I'd go with the bear!  Never mind that .44 Yellow Boy peashooter.  The bear has a weight advantage and is fast and unrelenting. 

Like I said, not a good situation!
