No Shortage of Boredom

 We finally got rain, after 20 plus days of 90 degree plus weather.  Despite watering the garden, it was looking fried by the heat, humidity and sun.  The zucchini plants are starting to die off with little harvest already.

Berries ~ Question

We don't have much to pick this year.  Too dry despite watering.  Zero red raspberries this year.

Does anyone know what this is?  It's a form of a vine growing in the trees.  It doesn't have any sort of berry on it either.
