I've seen plenty of black bears in the wild, but this was the first and only time seeing a grizzly. Definitely a highlight but I'd prefer to have a bit more distance if I come across one again.
Black Bears are considered more dangerous than browns. The reason is blacks are usually around heavy vegetation
and easily surprised at a close distance. Grizzlys are usually seen in open areas and know humans are coming.
Once again, I'm no bear expert. My father just taught me a lot about them during his time in AK.
