But I think writers, or artists in general, should never get too tied down with where they create, or when, or how.
I’ve been going over the notes about the story I’m picking up again after a hiatus, and I’m suddenly aware that my notes are confused about the sequence of places the characters visit (there’s only two, but in which order?), exactly why they’re going to one of the two places at all, and exactly who is going (well, mostly that’s clear, but half of my notes seem to assume that one particular character is going, and the rest don’t mention him at all — plus, if he does go, how are they going to fit in one car?).
So, yeah, maybe time for an outline.
