Our hosts, Les Fabulets, are members of a community vegetable garden collective in Rouen. They left the key to the garden with us, and encouraged us to go and pick what we liked from their plot. We enjoyed fresh cabbage, lettuce, carrots, leeks, beets, and other goodies all during our stay in Rouen.
