First time camping in bear country in popup.

I great many places I have camped have bears that might roam through even crowded campgrounds at night. Glacier NP is a prime example. There a grizzly is just as likely as a brown bear. There are exacting requirements posted on signs, at camper check in locations and at each campground. Not even water bottles are allowed left on picnic tables. You are required to clean up everything and put it away. Popups and even tents are allowed.
