Best hidden secret is the antique fair under the freeway overpass on 21st between W & X Streets in Sacramento. We discovered it on a whim as an excuse for a weekend getaway and now have gone back twice since that time. This flea market opens its doors on the second Sunday of the month between the hours of 6:30-3:00pm. Yes, it is in Sacramento which means an 1 1/2 to 2 hr trek for us living in the Bay Area but the non-city prices makes the money spent on gas seem like a bargain. The decent selection of mid-century furniture will keep me coming back.
