Herping (that means looking for reptiles and amphibians for the laypeople in the crowd - AKA: rock-flipping, log-rolling, bush-poking, etc.), camping, nature photography, canoeing, hunting, fishing, tropical ecology and conservation biology, reading, and squat thrusts. Anything outdoors really. I also enjoy flipping toothpicks inside my mouth using my tongue.
A bushmaster (Lachesis muta), a bot fly larva (one that is flesh of my flesh), Charles Darwin, Ghandi, Carolus Linnaeus, Theodore Roosevelt, and maybe your mom. Also anyone that isn't out for just personal gain, but actually wants leave things better than they found them. If you want to save the world (or at least its reptiles and amphibians) and have recently come into large sums of money to go in with me (I can contribute about $20 at the moment - maybe $40 if I ask my friends) to buy a huge chunk of land in Brazil to start a nature reserve and our own private research facility give me a holla.
You name it. Calypso, Maná, Rusted Root, U2, Radiohead, Dixie Chicks, Tom Petty, Beethoven, Jack Johnson, The Fray, Lynard Skynard, Enya, the Last of the Mohicans and Braveheart soundtracks, the list goes on.
Last of the Mohicans, Napolean Dynamite, The Mission, Three Amigos, Braveheart, Slingblade, Simon Birch, Life is Beautiful, Forrest Gump, A River Runs Through It, and Dumb and Dumber.
On the rare occasion I watch it, Snake Wranglers and the Jeff Corwin Experience...and unfortunately, now that I live with my girlfriend, I must admit to an episode or two of Gray's Anatomy.
Ishmael, A Sand County Almanac, The Hungry, Hungry Caterpillar, Jaguar, In the Kingdom of Gorillas, and anything by John Grisham.
Alan Rabinowitz, James Gibbs, Luiz Flamarion (the coolest mammalogist...ever), and the person that created Jelly Bellies and Rite-in-the-Rain paper.
