Last September they had their first open house, and, they are doing another event again in a few weeks. If it is even half as good as last time I highly recommend checking it out. It is a fundraiser for FoodShare which is also a great initiative. Cost is $10 per person but includes lunch and all kinds of samples. I know some of you missed it last time around (old thread link: http://chowhound.chow.com/topics/868820 ). Last year I walked out with bags and bags of fresh produce for free or by donation. It sounds like they have more organized "sales" of product at wholesale pricing this time around.
Here is the event link, I recommend buying it online so you can get into the parking area quicker -
I was impressed how well they had it all organized last time considering it was their first time, and I expect it to be great again this time around.
Unfortunately that is also Doors Open weekend so hard for me to decide what to do :)
