I'm going to San Diego this weekend after all. (I'd raised the possibility earlier in a friends-only entry.) I arrive Saturday afternoon about 4, have to be at the customer site about 2 AM Sunday for about 6 hours (estimated), and don't return for another day after that. I'd visit mr_fu and his roommate Nakko, but the former, at least, will be working all of the time that's interesting. Drat.
Even so, the trip is worth some real money, so I won't argue.
