True Blue LA, a Los Angeles Dodgers community

Tip to Diamond Leung's blog and his caption "Vin the Chick Magnet". Oops, I didn't notice that Diamond links to The Left Field Pavilion, where there is another similar photo as well. Judging from Vin's appearance, plus the hatted man in the background, and the general look, I suspect this is from Vin's Brooklyn days.
