Was in the 60's last week, down in the 20's this week, back in the 60's this weekend. That's TX weather for you!!
There's lots of fun stuff to do in Dallas/Ft. Worth. The 6th floor museum about JFK's assassination is very cool. There's a couple of great art museums in both cities. Lots of great restaurants - Downtown Ft. Worth is fun to go out at on the weekends. Some cool bars and music always going on. And so forth and so forth.
