Well, at least one reason...in H-town if you live ITL (inside the loop), anywhere you may want to go is no more than 20 minutes away. The city itself is very central even if the area that is considered Houston is large. In Dallas you not only have the surrounding cites of Dallas but those of FW too. The DFW metroplex is HUGE and can take forever to get to wherever you want to go. I am SO not into commuting!
And that's my 2cents for today.
P.S. Please Hurricane Ike pass us up so I can go home on Saturday.
