My husband and I have started to make the Falls Church Farmer's Market our weekly stop for fresh, local fruits and veggies. Of the 3 that are closest to us, FC is the best. Lots of vendors, including four different bakeries, Cibola Farms (Buffalo!), and several vendors with fresh eggs. There is also a plant vendor who sells lots of great and somewhat unique plants for your garden (the one around at the back end).
My only frustration is that the vendors don't have better signage so I know who I'm buying from.
