That, and no pets allowed, is why many folks don't go to shelters.
I guess avoiding a little second hand smoke is more important.
What if they didn't bring food, what if they need a bathroom (especially the kiddies), what if a small baby needs a warm bottle. Or what if they break down or run out of gas. They can't leave their cars. They can't go forward quickly and they can't turn around and go back.
Maybe it's better to be in that scary stadium than trapped on the highway when the raging winds smash into all those vehicles in a couple hours.
Oh my, this is horrible for all these good folks. I'm sure they are terrified.
