No, If I went to camp where there were grizzly bears I would have likely not survived such a an encounter.
Black bears are usually dangerous if the spend too much time around people which is why the parks no longer have dumps where people can circle their cars and hand feed bears candy and honey like they did when I was a child.
Has anyone ever heard of corduroy roads? During the depression the CCC built many structures in the park and “improved” the dirt roads by splitting logs and burying them in the dirt to give a flat surface to drive on. This worked about as well as you would expect in a place that gets a lot of rain and snow and most of the logs wound up in their most stable position, which was flat side down. Then they were blacktopped over giving a surface much like driving across the wales of corduroy.
