We went to Dallas/Fort Worth a year or so ago just for the art (3 days). And another 3 days in Austin just for the BBQ

. With only 1 1/2 days - I'd probably stay in Fort Worth. Do the Modern Art Museum and the Kimball. And the cattle drive in old Fort Worth too (which is fun). I would definitely try to get to the Nasher in Dallas as well for at least an hour or two.
Note that November 10 is a MONDAY. Lots of museums are closed on Mondays - including the Museum of Modern Art in Fort Worth and the Nasher - the only 2 I looked up. IMO - there is an awful lot to do in the area - and you're kind of shortchanging yourself by only taking 1 1/2 days - the middle one being pretty much a "closed museum" day. Maybe you can add an extra day to your trip? Or reschedule it unless there's another reason you have to be in the area then. Robyn
