1. The Hills Have Eyes
And if you think you can avoid danger as long as you stay off a plane, you've got another thing coming. Planning a fun family vacation across America in an RV? Aside from the boredom (seriously, there's a lot of states in the middle that might as well not even exist) and the very real possibility that you will all hate the sight of one another after about three days, you're not even taking into account the potential attacks from hillfolk. Because they're out there. You might not see them and they might not show up on any census record, but they're sitting out there in the desert, biding their time. Waiting for you to get overly optimistic with how far you can go on one tank of gas, only to end up stranded in the middle of nowhere. After decades of inbreeding and nuclear testing, these people are well and truly damaged, and looking for revenge.
