But I bit the bullet and started doing research, both on Carson's and traveling carnivals in general, and I think it's going to end up being worth it. I'm not going to stick like glue to the comics continuity, which might piss some people off, but my personal headcanon and things mentioned in WBP have him spending at least a little time in the military, so it wouldn't be exact anyway.
(Note to self: Now that I think about it, Koontz has a couple of older novels that take place in a carnival setting - The Funhouse (1980) and Twilight Eyes (1987) - so I might use them for a little secondhand research.)
So I'm going through the story so far and working in some references, which makes the editing process more interesting, and since I need to move some things around and do some rewriting of certain parts anyway, I might as well.
Honestly, this is the most work I've ever put into a fic.
