I've never lived in NYC, but I did live in the Boston area for 10 years, then moved to Northern California. For a while I was flying back to Boston every couple of months. I definitely noticed the difference in mood in Boston Logan airport vs. San Jose. The grumpiness of Bostonians was particularly evident compared to the relaxed, upbeat mood of Californians. Maybe it's partly the weather, but I suspect it's also cultural; I didn't notice it being any better in spring and summer.
