Lot of folks out here have coffee cans to deposit money into. It usually pretty simple set ups, a card table in the shade with produce on it. Its all on your honor, and most folks don't want to see anything go to waste. Id rather give it to someone who needs it than have it end up on the compost pile. Besides if someone needs to steal a coffee can with a few dollars in it, they got bigger problems than just needing fresh produce in my opinion.
My wife's dropped off a few boxes of our extra produce to the battered women's shelter last year. They are a stepping stone for women and their children to escape abusive relationships to help them get their feet on the ground and then move on with their lives. My wife's a nurse and was able to make the donation through one of the social workers at the hospital she works at. Few weeks later we got a letter thanking us as they were thrilled to have extra fresh produce since most of what they get is canned or dry goods. We plan on doing that again with our extras this year. Even if they are stubborn NE folk, if you look around you'll find someone who could put extra produce to good use.
There was a summer when I was out of work. My garden was more carefully planned out that year for things we could can, store, and designed to get the most out of what we put in with lots of proven performers and more hybrid varieties than I usually plant because it was all about volume for us that year to help cut our food bill. I was extra diligent too pushing to get the most I could out of it and it I know it helped us dramatically. Id always had a garden before but that summer it put a things in a different perspective and I keep that in mind now each spring when I'm planning out the garden.
