As an aspiring horror writer, living in a small town could be considered to be, in some ways, ideal.
Some of the best horror stories I've read seem to take place in small towns. Stephen King's IT, Peter Straub's Ghost Story, as just two examples. This is true sometimes of movies, as well. The reason this is, I think, is that there's just something about small towns.
For one, a small town is a personal place. Not too many places to go, plenty of people who you either know well or have met before--the familiarity of a small town, like Mount Shasta, is both beautiful, comforting, and when used correctly or looked at in a different sort of light, it can be just as haunting. Which is, I must add, also beautiful and comforting, in some ways!
Although Mount Shasta isn't haunted, at least not to my knowledge, it certainly provides that great atmosphere that comes along with a great and in some ways idyllic small town, and even sometimes inspiration. Admittedly, I've even wished or pretended for the sake of the feeling and emotion and for my writing, while walking through it in the emptying hours of the evening (as Mount Shasta seems to grow empty as evening progresses, giving it a quiet and sometimes eerie sort of feeling that can be, in some ways, sort of exciting), that it is haunted, or holds some sort of inexplicable secrets of that nature. Mount Shasta is certainly a perfect setting for a ghost story, in some respects I think, and I've always been intrigued enough with the paranormal to all but actually wish that it were a haunted town. It would be different, and probably exciting or at least interesting, in addition to being potentially terrifying.
There is of course that belief in being surrounded by spirits and paranormal energy at all times, and being a somewhat spiritual person as well as being a writer, I don't debate these sorts of things much although I do a lot of thinking about them, I find that there is a lot to be said about energy, and atmosphere, and history. Some places, for example, are better for creativity and for being open in those sorts of emotional ways, while some aren't. There's energy in the air, and the air of a small town like Mount Shasta is so peaceful, so quiet and lovely, and when looked at in just the right way, can be pleasantly eerie. Especially in winter, or autumn. I like to go on walks with music such as the theme from William Peter Blatty's classic, The Exorcist, and build upon those feelings and the atmosphere, and though I of course do these things for the sake of my writing, I also do them for my mind, and for the sake of doing them, which I think is an important thing in life. Walks are important, because they could be considered symbolic of allowing yourself to slow down, take a break, let yourself be out somewhere with just yourself and nature.
As for the idea of a haunted small town though, it's a scary idea, great and traditional towards the concept of a great horror story, and I think that it's just as wonderful of a thought as a normal small town, which in itself could be haunting. A person can look at life through any lens they wish, and what some would call the "darkness" can be just as beautiful as anything else, I think. Well...sometimes!
