Today, 25 tons of pumpkins were there for the taking by Sacramento kids. The Antelope Pumpkin Farm, operated by Antelope Christian Center since 2002, aims to put smiles on kids faces. They provided free hayrides, carnival games, face painting, bounce houses, arts & crafts and, of course, a free pumpkin to every child.    In East Sac the Shepard Garden and Arts Center in McKinley Park celebrated its 50th anniversary by holding their fall festival and annual sale, together, this weekend.    There's hundreds of arts and crafts, interesting plants, holiday decorations, lights, tons of books, and lots more miscellaneous stuff. The sale continues through tomorrow. Where: Shepard Gar
