At that hour, the only practical way to get to the airport is to drive; you can't take BART to SFO from here unless your flight is after about 9 AM. Traffic should be light, but I must remember that the San Mateo Bridge has overnight road work and drive by way of the Dumbarton Bridge. I considered taking one of the stay-and-park deals from a hotel near SFO, but as I'm only going to be away four days (Friday-Monday), it's still cheaper to just pay the parking. If the trip were for a week, then the stay one night/park free for a week offer starts to make sense.
Now, let's see if I'll be able to get to bed sufficiently early today to get a good night's sleep. I'll also take my neck pillow on the trip. You'd think that flying first class and sleep-deprived as I'm likely to be, sleeping on the plane won't be a problem, but sleeping on planes is almost always a problem for me. It's a sign of just how exhausted I was at the end of Norwescon that I fell asleep for the first 30 minutes of the flight back from SEA.
