Not wild, but yes, grapes. Well, wild in the sense that they are climbing the treeThe long, skinny ones are the tree. The others are wild grapes.
When I get home I'll cut into the fruit and snap a new pic. Perhaps plum, but there are no thorns. Do all plum trees have thorns? Thing is the fruits are falling to the ground before they ripen (unless it's a fruit that ripens with a green color).
The fruit is also somewhat fuzzy.
