Know your load. That's rule numero uno in this business, which is why I make them count the penguins out in front of me one at a time. I'm not going to be the schmuck who shows up in Orlando twobirds short of a dinner party....I know I'm pulling out of Houston with exactly forty-two Gentoo penguins, seventeen Jamaican land iguanas, four tuataras from New Zealand, and a pair of rare, civet-like mammals called linsangs. No more, no less.
