One of my special interests is fictional towns. Namely Ray Bradbury's Greentown, which was based on his hometown of Waukegan, Illinois. And Stephen King's Castle Rock, Derry and Salem's Lot, which are based on his hometowns of Durham and Bangor, Maine.
I grew up in Las Vegas, Nevada. Which was mainly developed in the 60's on up. So there's not much there that resembles what's described in the fictional towns I like. The really old neighborhoods there only date back to the late 50's. Things there to me are two dimensional and boring. The casino/hotels are more like Disneyland with fake Rome, Paris etc.
So I'm really fascinated with where I live now. The house I live in is over 100 years old, which is common there. All the houses look different. There's vary few "cookie cutters".
Downtown there's old brick buildings with fire escapes. There's a 100+ year old theater, hotel, library, courthouse and churches etc. The courthouse has a clock tower that bongs out the hours as do several of the old churches with their bell tower steeples. There's a big cemetery at the end of town with moss covered tombstones and giant trees (in Vegas they were just lawns with plaques ie boring, not the least bit spooky or gothic).
So I'm hoping I can take all of that and build a book on it. Something in the spirit of some of Bradbury's and King's books.
Another favorite fictional town is Twin Peaks, which was filmed in a town only about a half hour drive away. Although some locations were filmed in my town.
