VIRGINIA vs. WEST VIRGINIA

I'm about to go see the movie for the 9th time, but there's one thing I've been wondering that I wanted to ask you about! In the novelization of the movie, it seems that everything takes place in Virginia (I think). Even Somerset is in Virginia instead of West Virginia. I also noticed that both victims' cars in the movie have Virginia license plates. So, why West Virginia? Was that a last minute change? Did you guys realize that it NEVER snows that much anywhere in Virginia?? ;) Thanks!

Good catch! Late in the post-production process, we decided to change several locations in the film to West Virginia for the very reason you suggest.
