Wild Blueberry

Have you noticed the super abundance of all kinds of fruit this summer, both wild and cultivated? Recall last spring that it just never got warm outside, and it seemed like every weekend was cold and wet. Somewhere at a greenhouse my wife talked with a guy from Arkansas or Alabama and he called it a "raspberry winter." He said that a spring like that would result in more fruit that we knew what to do with and it's starting to look like he was right. We could attribute this to the abundant rain this summer, and while that certainly helps with the size of the fruit, something good had to happen last spring when these plants were flowering.
This Vaccinium was fruiting with more abundance and larger fruit than I had ever seen, at a sandy black oak savanna in Lake County, Indiana. It was a low shrub about knee high, and it is either Vaccinium angustifolium or V. pallidum. Can anyone offer opinions on the I.D? Thanks! I apologize but I didn't notice whether the underside of the leaf was pale or not.   Eat well, breathe easy, and thank a plant for both!
