I have a whole list.
New Orleans - humid, below sea level, fear of being disliked by voodoo practitioners, unwilling to whip off my bra for beads.
Washington, DC - I was afraid of terrorism before 9/11, also war, and figure it's still one of the most likely places for attacks. OTOH, I've been unemployed for so long now that if a job were to open up in DC, I'd probably go there.
Texas - humid, snakes
Florida - humid
North Carolina - only if they paid me well
Brooklyn, Queens, Bronx in NYC - crowded concrete jungles, polluted, expensive
and the suburb where I grew up
