It actually taught me to look for things I'd never considered before like paw paws and persimmons instead of just neglacted apple trees.
I'm noticing that now. Lots of trees produce fruit, but unless you know what it is, you tend to disregard it. My old neighborhood had a lot of feijoa being grown as an ornamental, and most people had no idea how good they were to eat. When they were in season I'd periodically just gather some, as they'd be all over the ground.
