It's when I consume several thousand calories in a few hours with no guilt because it's followed by walking around during that same time period so I can see all sorts of crazy sights, people watch to my heart's content, see what the hottest new "As Seen on TV" trends are, and witness some of the most gigantic testicles ever. This year I got to do it all in the rain, get hit on by a guy whose IQ and number of teeth are probably close to equal, and end the day by being strapped into a giant slingshot. Sounds like fun, huh? Today every muscle from the neck down is sore, I have a bunch of blisters, but I am happy.
If you want to know what the heck I am talking about, to read the details, and to see pictures pray I can make my camera and my computer play nice. Then come back tomorrow.
