Free Fruit from your Neighbors Answered
This nytimes article shows just how easy it can be to get free local fruit from trees in your neighborhood. If it's hanging over onto public property, you can go for it. Of course, it's even better to meet the owner and even trade some of your own bounty.
I do this pretty often. In my own backyard I get free figs from one neighbor's tree that extends into our space, raspberries off a vine on our fence and oranges from a tree in our yard.
