[TStanley]: I'm sitting in the airport in Tampa, Florida at the moment, getting ready to head home.
[talexb]: TStanley I'm flying to Vegas in two weeks time. After that flights leaving Vegas and Phoenix are late at night .. I've been hearing that it gets so hot that the air isn't dense enough for planes to take off. Weird. Guess you won't have that problem.
[Corion]: Yay, vacation time now - one week off work (but a Perl workshop in the middle ;)) )
