To the hills! You are on this site. You should have a bug out bag with at least 72 hrs of food available at all times, right?

You know how to boil water to ensure it is safe to drink and toilet facilities are easy to make. Unless you are not capable of walking 5 miles I would say you are better off hiding in the wild.

You can start a fire to keep warm while people in a shelter would be relying on fuel being shipped in or power lines.
