This is a link to a great blog about the Jan 2006 LSD Symposium in Switzerland. In attendance, Albert Hofmann, celebrating his 100th birthday, Alexandar Shulgin [ inventor of XTC], and Ralph Metzner [Leary associate].
There were potent commemorative blotters of Hofmann's famous bicycle ride [offline, I assume] at the symposium.
