That's pretty cool! I found different kinds of wild berries once; I asked a local farmer's market about them. Turns out that some of them were edible! I don't live near where I found them anymore, but I would encourage anybody to seek out and identify wild fruits - you never know what you might find!
At least my teacher thought it was good. She even took one apple for herself! Though I suppose that's expected, she's always pushing the school to plant gardens.
