Photography, computers, hiking.
Almost everything. I maintain a large MP3 collection covering everything from ABBA and Beethoven to Zepplin and Z-Z Top.
I regularly watch IFC (independant film channel). Lately I've seen The Last Kin of Scotland in the theater.
Six Feet Under, CSI, Gray's Anatomy.
Survival or Hegemony, The Art of Possiblity, Harry Potter, The Gap Series, The Belgariad, and the Lord of the Rings.
Che Guevara, Fidel Castro, John Kennedy, Dalai Lama, James Randi, and Pierre Trudeau.
