Sport day in Osojca

We're collaborating with elementary school Miroslav Vilhar for some time now. Each time as the school year is ending we organize sport day in Osojca cave. The kids arrive on bicycles and then divide in two groups. One goes in the cave while the other tries climbing techniques at the entrance. After that they switch. Some kids avoided mud while others enjoyed it and came out of the cave unrecognizable. But why worry? Mama will wash it all.
