Museum day. Archaeology was the most interesting with the Zagreb mummy with its bandages, which from a linen book. Ethnographic Museum was full of native costumes but way overdoes it for the casual observer. Croatian Museum of Naive Art had an interesting display of local, non-professional paintings. Botanical Gardens is small but a nice spot to get away from the city.
Much of the day was about hanging out at the cafes, the way the locals do it.
