I think I'm going to be able to work out a schedule with my wife's Tues/Thu kickboxing classes.
Her classes don't start till 7:30 so if I drive (sucks I know) up to SF for a 6pm start, I'll be able go for 1:10 or so and still make it back for her to get to class. Worse case, we can put our eldest daughter in charge for 30 minutes until I get back.
