"What prize are you giving away?" I asked.
The person behind the table pointed to a pair of bicycles. Hmmm. Don't know what I expected: handcuffs, maybe? A shoulder holster? A blank signed search warrant? Anyhow, apparently they're hiringg. Division of Fish and Wildlife had a huge booth and had various pelts, including two from the non-native phythons in Florida that have taken to eating pets and pigs and whatever else they want, because there are no natural predators for pythons in Florida. They'll be lucky if they don't end up like Guam, where the brown snake (an inadvertent consequence of the vast number of combat planes arriving with stowaways during World War II)has consumed virtually every species of bird to extinction.
Health agencies also sponsor booths, and my favorite was the one with the walk-in colon.
