More rocks

Enroute to Stockholm we stopped at Norrköping to the joy of the kids. The area is reknowned for its petroglyphs. The field at Himmelstalund has 1660 carvings of ships, hunters, wild boar, foot prints and what not. Amazing in amount and detail and nearly 3000 years old although Rita insisted that we don't know if a spaceship just dumped them there in the middle of the night sometime.
