Teddy in Amsterdam # On his trip from SFO back to Europe teddy spent a few days in Amsterdam. He brought back the following pictures of bikes, cheese and the canals: Going to Amsterdam usually is pretty darn dangerous: I tend to return with some toys added to my collection of puzzles. Somehow I tend to be drawn to the shop called Gamekeeper selling them even when I do not remember the exact address or even just the street name:
