I lived in Houston for my post-doc and then my first job after it… and fell in love. The only place that I liked more was Dallas. I used to go to Dallas once a month or so. From those trips I discovered Ft. Worth and the whole area. I made a lot of friends in the area (From an Atheist/Agnostic chat room, to a multi-line BBS in the 80s) and I enjoy reconnecting with everyone when I visit.
It has a large Asian population (though not as big as Houston) an active gay scene and a nice “Alternative” area.
So when I get the chance for a vacation, though few and far between…. my number one city to visit is Dallas.
So… what city is yours to vacation to ?
