It was the Labor Day holiday today in the United States (so: no work), marking the unofficial end of summer. Back to school for the kids this week (finally), and back on the road for me. I took a late flight out to San Francisco. Our workshop starts too early in the morning for me to make it in with a morning flight. I took a taxi from San Francisco airport for the 14 miles or so to get me to the hotel in Fisherman’s Wharf. Kind of too late to take BART, and the Embarcadero station is still 2 or 3 miles away from the hotel.
