Meetup at After Dark at the Exploratorium. You need to buy tickets. Meet outside the exploratorium at 6:15pm by the vertically orientated sign with the big hole. I'll also try and be near the entrance inside at 8pm if you're running late and want to find the group. There will likely be post-exploratorium drinking (venue TBD).
I dunno, I've missed all the others and well... Stampede is people + party-time, no?
