Any fairly cheap park/farm venues for a wedding in Bay Area or surrounding location?

it's going to be very expensive actually if you want to do your reception in a park. tho the park fee may be small, the cost of a tent rental can be $5000. plus tables & chairs, that's another thousand bucks. it's probably better and easier to find an event venue that's already set up for weddings rather than piecing it together yourself in a field somewhere. search for venues on weddingwire.com.
