Oooh, within driving distance of Tacoma!
Is there a way to RSVP other than through Facebook? I'm one of those Luddites who refuses to use Facebook because of their history of privacy abuses.
RSVPing through FB doesn't guarantee you a spot, just gives them an idea of how many I think. You'll still need to show up early to get in line to get in.
Keep in mind this is during PAX weekend, so there will be 70,000 geeks in town, and a portion may be attempting to attend this little shindig.
