Hey JimT! This made me think of you...
That's from the park out in front of our house. Unfortunately, there's something about the soil or the trees or ??? that renders them unpalatable to humans. The dogs, on the other hand, love them. Our Biscuit dog is a regular mango hound. She considers it her duty to scour the ground under the trees in search of mangos green or ripe of any size that might have fallen since the last time she was there.
