In Marin City, California, between Sausalito and Mill Valley, there used to be one of America's greatest Flea Markets on the weekends.  You could find everything from an 1850's hand-painted room screen to an Italian street punk switchblade.  The food was wonderful, from fresh croissants to spicy Thai noodles to pizza. I kid you not, this was the best...I say "was" because it is now a mini-mall...a sure sign of progress.
