Here's one more reason to visit the Green City Market during the (fingers-crossed) beautiful weekend: restaurateur and author Alice Waters will be there on Saturday signing copies of her new book, "The Edible Schoolyard," according to the Tribune's food blog, The Stew. The book examines how the "slow food" pioneer and a group of teachers turned a Berkeley middle school's land into a garden.

Waters will be signing from 10:30-11:30 a.m. at the Peggy Notebaert Nature Museum, then touring the market (open from 8 a.m.-1 p.m.).
