The event is free and includes numerous vendors selling all kinds of crafts, art, breads, candies, various services, and a wide range of food. There are also street musicians and artists numerous people espousing varied political views, walking around with placards and handing out pamphlets. People seem to come out of the woodworks for this to show themselves off, meet others, or people watch and the event draws a wide range of people, including some very interesting folks. Some people come quite a distance to go.
It can be frustratingly crowded at times, but is also fun.
I should add that this is not Santa Rosa's "real" farmer's market, as people sometimes seem confused and the farmer's market portion of this event is limited compared to the large, regular farmer's market. The real farmer's market takes place every Saturday until noon all year long at the Veterans' Memorial Auditorium at the corner of Brookwood and Maple, across the stree from the Sonoma County Fairgrounds. It also is every Saturday except when the Wednesday Night Market is going on.
