I have very limited experience in grizz country - exactly one overnight in Denali NP following three weeks on the big hill. We were in country where grizz had been reported recently and we were very scrupulous in our conduct - cooked at a distance from our tent = stashed food and smelly things also at a distance, stayed together and made noise in thick brush, etc. It was one of the most pleasant camps I have ever made, with magnificent vistas and a gorgeous sunset. We did not carry bear spray. I don't believe it was in common use then (1987).

In grizz country, play by the rules for avoidance. Keep a clean camp and be aware. There are gratifying rewards. And be aware that are plenty of more mundane, commonplace hazards which will get you just as dead.
