Fannish party at the Savitzky residence, AKA Grand Central Starport. This attracts lots of, er, Interesting People -- science-fiction fans, filkers, and the like. It's at 343 Leigh Ave, San Jose, and runs from noon to midnight or so. I typically turn up mid-evening and stay until elevenish. People are encouraged to bring food and/or musical instruments.
If it rains, I'll show up earlier... if it's sunny, the tidepooling is on, and I'll show up mid-evening as usual.
