ah my friend, if only I knew
Thank you very much, by the way.
My personal take on it is based on two reasons: historical and geographical. Historical, because it's one of the oldest states, and thus has more "history", so to speak. There are quite a lot of old money/families living in the area and with that comes the political and financial influences that might have brought some of the artists to live in the area, if they weren't born around here to begin with. Providence, RI is also a haven for artists and intellectuals with many famous schools and colleges (the two most famous are probably Brown University and Rhode Island School of Design aka RISD), and it tends to reflect on the atmosphere of the place, I think. Geographically speaking, the landscape and old Victorian architecture are prone to exhult wild imagination bursts, perfect for a Lovecraftian novel, for instance, or a Poe lamentation. The weather is inconsistent and certainly has some effect on the psyche of the people living here. It can changes radically in 30 minutes from sun to snow, and it does happen. Such extremes do help depression, I would assume, or at least certainly influences the finding of those hidden dark places within the confinements of one's inner self.
I blabber, but the place is old and the memories of time are present. It's up to the individual to see or feel them.
