Well, this probably makes it official, I'm insane. I've booked a flight to Washington Dulles International Airport for tomorrow night and to return on May 20th. The only thing left is to rent a car for the duration of the trip and find couches to surf on. Once back in Las Vegas I'll be renting another car and driving to Los Angeles and San Francisco, returning on Sunday, May 31st.
As for the CHI/GH annual gathering I've also booked my flight to Chicago for the evening of July 16th with a return flight on July 20th.
I still have a credit with AirTran that will be expiring fairly soon, if not already. I can't seem to find any emails regarding it, though, so I'm not sure.
