Spring breakers: Surprisingly courteous. This year\'s revelers are the most polite yet, said Marie Squillante, 77, who owns New York Pizza, a block from the beach. "They\'re so respectful," she said. "They say \'Thank you,\' \'You\'re welcome,\' \'Please.\' I\'m shocked!" But Leah Kavalec, 20, a student at Ohio State University, admitted that she had been asked to turn down her music and dump out her beer.

Sharks: Bites are rare. Nonetheless, on Friday a shark nipped a 13-year-old boy on his ankle in New Smyrna Beach, the second such encounter of the year in Volusia County, the world\'s capital for shark bites. But Volusia County Beach Patrol Capt. Scott Petersohn points out that most bites are minor and aren\'t "attacks" as much as cases in which sharks mistake hands or feet for fish. To protect yourself, stay away from murky areas with small fish that sharks like to prey on.

Concessionaires: Desperate for your business. Dave Durante, who sells ice-cream bars and cones out of a truck, estimated that business was down a third from last year. Matt Conway, who rents all-terrain vehicles, said the same, though Greg Caldwell, who sells hamburgers with Greek seasonings, said he hopes pleasant weather brings a boost in sales this weekend. "It\'ll be a real good weekend," he said. "We\'ve got a good tide and a good forecast."
