Since living in NoTx, I have come to the conclusion that I like Dallas well enough, but am glad I don't live there. Visiting there isn't bad. Some decent places to eat, some good museums, some interesting things to explore. The overall attitude of the majority of folks I've run into, though, seems to be either: (1) I live in Dallas and I'm a rich badass and you're a slug, or (2) I wish I could get out of Dallas because all these snobby people drive me nuts. You can see the vicious cycle. I agree that watching the Cowboys' train wreck every fall can be really darned entertaining. Unlike other non-natives who've moved up here, I don't actually hate the Rangers, but they're not *my* baseball team. I've felt very discombobulated this season because, no matter how awful the Astros do, I can't turn on my tv and see them live. Unless they're playing the Rangers.
I worked in Fort Worth for the first 6 months that we lived up here. Fort Worth people generally seem to be friendlier and more down-to-earth than Dallas people. Everyone I've run into in Fort Worth who's learned I'm originally from the Houston area was pleasant and had nice things to say about Houston, or they were very welcoming. Almost every native Dallas person who's found out where I'm from has wrinkled their nose or said something to the effect of, "Well, I can see why you'd come up here!" (You can? Interesting.) I liked working in Fort Worth, but the drive (among other things) finally got to me.
Denton has a good feel. It's part college town, part bigger-town-than-a-college-town, has a good music and food scene, and there's always something to do. Tons of lakes nearby, football, roller derby, hiking, camping, state parks, lots of outdoor stuff, but it's still cultured enough to have ballroom dance lessons and wine tastings if you're into that. Denton reminds me somewhat of Austin from the few times I visited there in the late 80's and early 90's. It's laid-back when you need it to be, but close enough to the cities that you can go there easily.
But don't let anyone who's lived in both places tell you the traffic in Houston is worse than the traffic in Dallas. My entire life until 2008, I lived within 2.5 or 3 miles from the Gulf Freeway, and that entire time, some portion of the freeway was being worked on. The traffic in Dallas is much worse than the traffic in Houston. Dallas doesn't grow its freeways.
