TURF CLUB CUTE: Oh, Arcadia. Just your name. Your beauty. Those mountains and palms and that glorious arboretum. And Santa Anita. Every chance we get to send some snoggles your way, we take it. And we want to tell people, other Arcadia aficionados, people who love the ponies and the pretty, about this offbeat necklace from Black Sparrow Jewelry. It is a locker medallion from the LA Turf Club; locker #694, to be exact. Could that be your lucky number? GIDDY UP:It's $13. We'd wear it to the track first chance we got.
