The Vienna Farmers' market is in the parking lot across the street from the Freeman House on Church Street (intersection with Dominion Road).
You can browse around and get a bunch of grapes (fresh) or an apple (fresh) or some lavender to throw in the dirty clothes bag to make it smell better or some homemade bread (fresh) or jams and jellies (not fresh but homemade). They have various types of honey and fresh flowers and kettle korn (my personal favorite) and homemade soup ingredients (just add hot water) and some local artsy/craftsy vendors showing their wares.
My wife takes about an hour to sniff around and feel and examine everything while I tag along behind ("yes dear!").
The market is setup every Saturday morning during the summer.
See you there!
