It was a good day to learn new ways to make a pumpkin pie — or pumpkin pi — at La Jolla Shores on Oct. 29. The Underwater Pumpkin Carving Contest brought out divers to come up with the best designs (nondivers participated, too, but competed separately). Diver entrants brought their own hollowed-out pumpkins and carving tools, suited up, then hit the water. Costumes were optional; neoprene was necessary.
