Tim O'Reilly's annual summer camp out on his Sonoma County estate, Foo Camp, is invite-only and a hot ticket in Valley circles. With a temporary helipad being built on the grounds one year for Larry Page to drop in on a gas-guzzling whirlybird, it gets more posh by the year. And according to Twitter's Alex Payne, maybe a little more debauched as well. In other words, it's beginning to sound more and more like the Valley's answer to nearby Bohemian Grove.
