Nobody hopes for a war or a natural disaster or an alien invasion from beyond the stars, but they like to know that if any of those things do happen their family will all be on the same page about where to go and what to do.
Emergency Plan hopes to do that by keeping meeting locations, contacts, and even basic medical information all in one place so nobody has to dig or guess about anything while they’re running in a zigzag fashion down Main Street to throw off the cybertanks’ laser-guided heat rays.
Or if there’s like a tornado or something. Either one.
