Your SIL has a charmed life for certain-never heard of anyone who went on “real” camping trips unarmed-I certainly don’t-my 1st hubby and I camped all over Texas and New Mexico-took our cub, too when she was a kid-but even in the Guadalupe Mountains we were both armed because of the black bears there...
I agree. She was counting on her husband (wife's brother, big guy) to protect her. That usually works with humans... but grizzlies? Come on, lady.
