In Michigan, black bears are abundant throughout the U.P. and much of the northern L.P. I use to tent-camp, but the first time I saw a bear paw-print in the dirt was when I bought my first hard-sided
trailer. Those paws are HUGE! And they have CLAWS! And brown bears are even larger! It just makes sense to keep all food and cooking items in a plastic bin w/tight-fitting top; then put that inside your locked trailer or tow vehicle. Yes, it takes a little time to allow the grill to cool down and to stow it away. So start dinner a little earlier to allow for that. Sure beats the alternative!
Due to the severe drought throughout much of the West/Mid-west, many campgrounds have banned open fires and outside cooking - even on a grill. So you either cook inside, or prepare meals at home, pop then in the freezer, and heat them up in the microwave. And microwave reheating leaves more time to enjoy the great outdoors!
