SOUR POWER: Disney’s lovable “sourpuss” — Donald Duck — poses with largest sour fruit grown at The Land pavilion at Epcot, the “Nine Pound Lemon.” With their descriptive name, the fruits from these trees weigh approximately nine pounds and preserve all of the taste of the smaller variety. Guests to The Land see the giant citrus on the “Living with the Land” boat ride through the experimental greenhouses housed inside the pavilion. Epcot is one of four theme parks at Walt Disney World Resort in Lake Buena Vista, Fla. (Photo/Diana Zalucky)
