A young couple receives a strange letter from their future selves, detailing the exact steps they must take to ensure their survival once the world ends in less than 2 weeks. But can they actually trust future them?

Throwaway because I need help with details. NOT INTENDING TO COPY ANYTHING.<br><br>**EDIT2**: I've been working on the story and it has a shot of being completed. <br><br>**EDIT**: First off, insane thank you to EVERYONE who gave me comments. I was NOT expecting this many. It's definitely given me a lot to work with and I think I've finally settled on setting up the story in a way that works. Thank you to the person who suggested Google Maps as a possible way to describe the route. <br><br>Now the question of what consequences will occur if they don't follow the letter exactly has been touched on, but it's not entirely clear. What exactly is stopping them from going off route and being careful during their stops?
