My dog and I (she was leashed) went for a walk yesterday on Belgrade's GREAT WAR ISLAND in the Danube River. It was overcast, few people. A lovely, sylvan walk, and despite the possibility of running into (or away from....) feral piggies, I saw nothing bigger than a butterfly. Note: Never run from them; walk backwards slowly or climb a tree. Walking backwards I can do, but forget the tree climbing....
