I wasn't aware of the books until my 12 year old Granddaughter from Houston asked me if I knew where Forks and LaPush were. Huh?
She then went on to tell me about the books. She was thrilled that not only did I know where it was, that I had actually been to Forks, LaPush and First Beach, and knew people out there.
My wife, who is a book seller, filled me as to the whole "Potteresque" phenomenon. We sent our GD a bunch of t-shirts etc. from there.
So now Forks is on the national radar and folks are coming to see what's in mentioned in the book. Ride the wave, Forks, because it probably last until the next teen book stirs the imagination.
