Zruč ball area

In Zruč, there is an unusual thing in the area near the school canteen (5. května street). Part of the publicly accessible playground with various rope "obstacles", which we also know from elsewhere, and the children's transport playground is a ball track. Both children and adults will go crazy on it (tested). Admission is free, but bring your own marbles. And you'd better take more of them, sometimes one won't stay on the track and ends up in the lawn...
