I just got back from Seattle, where I enjoyed the "Farm Fridays" section of Pike Place market, plus all the flower vendors. Sunday's Ballard Organic market was wonderful, too -- I came home with a 2-oz packet of morels for about half what I'd pay here in NYC. These are definitely local folks.
The farm stands at my local once-a-week Greenmarket in NYC are also local -- when it's not in season, it's not to be found. Just over a dozen stalls, but a great neighborhood resource, with folks from all walks of life snapping up the good fresh stuff, and a trio playing music. I love to go with my camera for great people-watching.
I wonder what market cpx is referring to? The Greenmarket system here is supposedly pretty strict about forbidding "foreign" produce.
