A Very Berry Summer

This week we have found several berries along our back fence.  We definitely know that some are blackberries, but we're not quite sure what the blueberry/grape-type things are.  Here are some pictures of the black and red berries in our fence: 

We only picked the black ones.  

They are guarded by some nice foliage.  

They are also quite large, as referenced by the golf ball.  

Since these berry findings, we'd like to make the most of their produce next year by trimming up the plants where they grow and tend to them more.  This house and its yard is full of surprises.
