Cowboys. They can disappear forever, and I won't miss them for a second.
Can't get on the "Texas hate bandwagon", but I don't care for the city of Dallas at all (having lived there for a short time). I often joke it should be considered part of Oklahoma. The smug in Dallas is palpable, and they have nothing to back up that smug but a big ugly city with almost no personality. Seriously, the golf ball and the Gumby building are their feature landmarks...
