I'm flabbergasted that Houston made that list, although I'll reluctantly acknowledge I've a nephew who lives there and seems tolerably pleased.
When I think of Houston I think of hideously high humidity, no zoning laws, and roaches the size of SUV's.
And
traffic.
Austin's gotten so big and chock full of "foreigners" (non-Texans), it's
completely changed the character of the city.
Plus the traffic is ghastly.
