You can't yet, but it's fine! I do that a lot too.

As for where it's taking place, I'm a bit hesitant to give a city just because then people think they have to go exactly how that city looks and whats in it. Which I don't think should be the case. If you want to make up a store, do it..

Anyway, I was planning on the city being Seattle. Because I'm familiar with the city, it's climate, and its a drive to huge forests.
