We are challenged by this one. Can you tell us, does it have any thorns? Was the fruit as blue as this photo seems to show? Does it seem to be a vine, or is this multiple plants together?
Our first thoughts were hardy kiwi or wild grape, but that's not quite right.
Any additional info or photos you can share may help us to correctly identify this one. (you can reply directly to this response).

Yes it does have sparse thorns. I didn't notice them yesterday.  I think I figured it out.  It's greenbrier.  Thanks!
