Not sure if it was an official farmers market, but folks in the office
called it that, and I think it was just once a week.
One day I went into work very early.. I saw some "freshly frozen"
vegetables were being unloaded from a truck.. hence my earlier comment.
I don't know how long ago this was... as a guess this was an official Greenmarket before 9/11, but at some point after the PATH station reopened an opportunistic market popped up. As I mentioned, it's not in the official Greenmarket directory.
A year or so ago I was looking for chanterelle mushrooms. I asked the mushroom lady at my local weekly Greenmarket if she ever had them, since there weren't any on display. She looked both ways and then leaned to me and murmured that she wasn't supposed to sell them because (I can't remember the reason -- either they had been shipped in or the quantity wasn't sufficient to stock) but she did have what I was looking for
(they were fresh and delicious, even if their carbon footprint was oversized). Point being that the vendors really are careful about following Greenmarket rules to maintain their eligibility... but that private deals might take place now and then.
And now the best part of summer has begun: the local organic heirloom tomatoes are in. The BEST!!!
