They're all over the place here, though you have a short window of opportunity to gather the fruit before the birds go apeshit and eat it all. I've had delicious jam made from it. Quite a sweet fruit, with no bitterness or tartness, unlike a lot of other wild edibles.
I don't know the species, and there are a few that are found in my area. One day I'll bring the field guide and figure it out.
