PHOTOS FROM AFAR

So my friend Thomas went to Zambia last week and sent me back some pictures. I'm not quite sure why he was in Zambia. I'll have to ask him.

But anyway, he sent be this photo. It prohibits something, but I can't figure out what.

No picnicking? No stacking objects? No playing chess with the lower 3/4ths of a pyramid? Julie believes it means no roadside vending, but that's just absurd.

Any suggestions?
