Veliki Ostros Off The Beaten Path

On the side of the road, in the middle of nowhere, a road sign warns "Beware, school !". However, these two guys seem to run in such a hurry that they cannot possibly run to school but out of school. I feel the sign suggests better playing hooky, what is called in French "école buissonnière" ("bush school") ! Actually, there was a tiny school, which did not look to be used anymore. When it was used, I wonder from where did the children come as the nearest hamlet is several kilometers away !
