At Houston Hobby, passenger Roy is going to the Mardi Gras where he and a friend are in the costume competition. They'll be the Lovebugs and they're hoping to beat their arch rival, who's going as the caterpillar from "Alice in Wonderland." And at BWI, participants in the Hogs and Pirates gathering are heading to Tampa. It's Florida's version of Mardi Gras, and the airport is filled with a few fake parrots and some pig's noses.
