Silver Back Brown Bear in Hoonah, AK (Grizzly Bear)

I downloaded some pictures onto the computer and found this video of the Grizzly at Hoonah. I forgot all about it.
WARMING - IT COULD MAKE YOU DIZZY! i was riding in an ATV on a bumpy road. We were trying to catch up to the bear to get a look. This bear is estimated to weight 450 pounds.
The fellow I was with had bear spray but he said he did not feel it works very well. When we got out of the ATV, he forgot the bear spray anyway. This is my encounter with a Grizzly Bear in AK. It is only like 17 seconds long.
