At least I still have the pictures of a real one.
Close to lake Oldambt there is this open air theater. It is inside a nature reserve area called Reiderwolde. About a twenty minute bicycle ride from where I live.
Took this photo a few years ago. Really hope winter will return one day to our region. These autumn like days we have now are not my thing.
