Er.. right. Well, art, music, science, travelling, nature, computers/computer games, movies, singing, rock climbing, skiing, camping, good books and B.S.-ing with friends.
Hmm... that is a bit tough to squeeze in here. Let's just say I like a ton of music. And the music I like doesn't include anything where anyone lost their pickup, sings about their "grill" or has a video with them attached to puppet strings.
A little bit of everything, but definitely Fantasy, Action, Comedy and Sci-Fi.
I don't really watch a ton of TV, but I do like LOST and Stargate.
Douglas Adams, LOTR, Richard Bach, R.A. Salvadore, J.K. Rowling, Dan Brown. And I like to read books that aren't fiction. Bizarre, I know ;)
