Thanks to having put in extra time earlier in the week and doing a bit of Day Jobbe work this morning, I only needed to take a half-day off from work, thus preserving an extra four hours of PTO for future Worldcon/Westercon/NASFiC trips.
The folks at the Wigwam restaurant know me too well. When I strolled in just after they opened at 6 AM, my usual server said, "You must be heading to the Bay Area today" because that's usually the case when I show up very early on a weekday instead of mid-morning on a weekend.
