Ouch, Joe! You're really lucky that didn't turn out much worse than it was, where I live in CA, I see a lot of accidents of that caliber but the drivers tend to not make it out as well. One of my friends hit a tree and broke both of her legs as a result.
As for me though, I'm mostly afraid of chimpanzees... they just give me the skeeves not to mention that there are so many horror stories of people being mutilated. Monkeys tend to freak me out as well. Then there are also like a bunch of other little things that tend to set me on edge but I don't tend to really recall them until I'm in the moment.
