Yea that sucks. From the looks of it and the time you mentioned it sounds like a hit and run. Either way you should be ok insurance wise as you were clearly not in the wrong. As for the damage, as others have stated, just pray there is no frame damage or the car is as good as done. Don't know what part of Texas you are in but the drivers in the Houston area are terrible. My wife is from there and I'm always amazed at the lack of driving skill I see when I am out there.
