Hard for me to judge an entire state without exploring the whole thing, honestly. I know I don't like the megalopolis of the eastern seaboard, it seems overcrowded yet horribly lifeless to me. I also don't much like the general attitudes of humankind residing in the infamous "bible belt"... but of course the truly, annoyingly zealous among those folks are actually just a vocal minority.
I can say one thing for certain though. I hate swamps. Every time I've been to Arkansas, Alabama, Mississippi or Florida, I've been in a fucking swamp. Hot, humid, no breeze for days at a time... fuck swamps. Not to say that's all that exists in those states, but that has been my experience with them (which, admittedly, was always just military training, so of course they took me to the most miserable backwater hole in the state).
As for states I love... anything bordering the Pacific and not too crowded. I've been all around the world, to many different climates created by many different types of topography and bodies of water, and there truly is nothing like living next to this particular body of water. If I leave it again, it won't be by choice. I want my ashes spread there. From a coffee can.
