Have you read The Tragedy of the Commons?

So F.R.O.G. fans, I pose an idea to you.  We of course have land.  Many of our friends in town don't.  I've considered a CSA, but there are a few details of them that I don't enjoy (such as charging my friends).  What about a COA... Community Operated Agriculture.  We don't charge you, nor do we drop food off to you.  But if you're looking for good tomatoes come pick a few. If you got some spare time and are looking for some relaxing time in the sun, come weed a row or two.  Grab a squash while you're here.  You get the idea.  My job would be to organize and regulate.  Dot the I's and cross the T's.  It goes against the lesson of The Tragedy of the Commons, but what do you think?
