I'm going to be in LA for work from 3rd – 5th August, then flying up to SF on 5th for ISEA and some other work-related stuff before going back to the UK on the 9th.
I'm probably going to try and round some LA people up for the evening of Friday 4th, but I'm up for beers in SF on Saturday night and/or a Sunday afternoon something (doesn't necessarily have involve beer, but hey…)
If anyone is at a loose end in my SF-vox-hood and fancies talking nonsense with a jetlagged person, then let me know!

word. do you still have my number?
I think we may hve some crossover time in SF, and if we do, let's try to engineer an alcohol fueled bout of foolishness.
