Boooored

So my last few days in Houston are very boring. Besides packing not much else going on. I really was trying to travel to a foreign country nearby, but since this was a last minute type of deal, the flights just did not work out: not much was available on the days I wanted it.
Continental, you suck!
So what is an SD to do in Texas for a few days, with nothing else to do? Anyone from around here? Any ideas?
