I'm in, wherever you decide to go! The weather is just perfect for it, too. You could always go to Texoma...it's about the distance you are talking about, and you could stop at Pompanos @High Point Marina before heading back. If it's just the DFW area you want to be in, definitely make Stroker's one of your stops. Can't forget Reno's Chop Shop, either.
(Just an aside: I'm going to Austin with my biker friends for Marley Fest soon...so far we have a total of 6 bikes going down there if anyone else has a hankerin' to go:
