AKA Monet's post reminded me of one other thing. Plano people have several nice hang outs. Jack Astor's being one of my favorites. But they all head down to the Richardson bars because everything closes up in Plano at midnight. 1am on Saturdays. Richardson is 2am.
Denton had everything closing up at midnight also. But that was good while going to school at UNT. Kept me from staying up those extra two hours the night before class. Unless I was at an after party.
Dallas & Addison close up shop at 2am. Not sure about Arlington.
