To be honest I'm not sure which chase happened first as the I didn't want to figure out which cam was lagging as these broadcasted at nearly the same time. I probably have it backwards and it started in the falls, but I like the riffles clip more. In the second clip 503 is the giant blocking the view and is likely the bear 912 is looking back at as he pursues 913 up the bank.
