Ya, I think gd is faar more familiar with DFW than me - I know they have some nice clubbing/bar districts, museums, shopping, parks and campuses - but I haven't really been there that much. It's really spread out. I periodically go up to a Taijiquan class or visit some friends, but that's about it.
And not sure what all you're into - but if you like paleontology there's Glen Rose
dinosaur track park about 80 miles SW of DFW. That's actually pretty famous nationally, although I haven't been there myself yet.
Well, if you guys try to set up some meet-up, I might be able to drive up depending on when exactly it is... Also, I can give you some more tips on Austin, if you intend on passing through there. Anyways, come on down and welcome to the Dirty Souf, yo!
Woa, I just noticed today is my 2-year anniversary here! Wow, time suure flies!
