It's partly navigational and partly just "feel", for lack of a better word. My lizard brain tends to be really judgmental about certain pieces of geography, like cities: it doesn't grok NYC or Baltimore or DC, but does fine (and has always done fine) with much of Philly, all of Richmond, and most of Boston. There's something about certain cities that throws off my (usually excellent) sense of direction. Plus, these are just places that I can't "get" on a level of "why would I want to live here?"

Parts of Boston throw off my sense of direction and I hate driving there (JP/Roxbury/Dorchester in particular), but I still love the idea of those neighborhoods as much as I love Camberville and environs.

(I also have an inherent loathing for certain states: Connecticut, Maryland, and Illinois are the top three that I can't wait to escape once I'm in them. It has nothing to do with history or anything else, because if that was the case, Virginia would be top of the list. I think it's just, as I said, my lizard brain being judgmental.)
