For us, we have several options. Assuming that we're bugging out instead of bugging in, my first choice would be to find a hotel away from the unpleasantness. If that can't work for some reason, we have smart, well-armed and well-prepared friends ten miles away. My wife's parents live fifty miles away. Another set of good friends who would take us all in live 500 miles away, and my mother lives 800 miles away.

The key is having enough information to make an intelligent decision.
