T.K.
JFK Museum in downtown Dallas is not boring! You can do the tour of Dealy Plaza too. There is also a Holocost Museum. When my girl was 14 those macabre things worked perfectly with her teen angst! Then go to a downtown restaraunt for lunch or dinner. Maybe Dicks or something posh in one of the downtown hotels. Have yall toured the New Cowboy Stadium yet? That's really cool if she likes football at all.
