I was going to tell you a quick way to tell if they are black or grizzly. A grizzly has a hump on his back above his shoulders but you probably already knew that ; )
I’m aware of the general differences between grizzlies and brown bears (the latter now have populations where I live.) But these bears were across the road, and I wasn’t about to get out of the car to make sure what they were. They were very large however and did look like grizzlies.
