This is great, when you don't have family with a garden, it's hard to take your kids somewhere to pick fruit straight from the tree.
except most of these trees grow usually next to frequented roads and I would pass on fruit exposed 24/7 to gases from cars
Is that still a concern? It used to be a major health issue when I was a kid because of tetraethyl lead pollution, but now that leaded fuels have been banned long ago, the car emissions should be harmful only to breathing and climate change, without any poisonous residue on roadside plants.
