Rodents, of all sizes. Sharks. I like a particular beach in SoCal because I almost always see dolphins/porpise (or whatever the heck the plural is-porpii? porpises-which reminds me of that Civil War thread and urea...) Singing in public. I figured out the other day that some people do extreme sports, I get my adreniline rush from singing in front of people. I get the same rush from public speaking, but it is not as intense because although people can disagree with my point, perspective, or politics, I wouldn't believe them if they said that I was flat or sharp or just off key.
