Dumped laundry, moved hotel to Colonial Palace on the same street ($35), which I booked earlier. It was not a good move: noisy (a church group did a long sermon in the early evening that day), thin curtains. Reliable hot water.
Went to the fair at the Huancaro suburb. Apparently this had been going on for a few days already. Pet zoos / vendors for alpacas, llamas, cows, guinea pigs (s/20 live and cute) and rabbits. Endless stalls selling various produces (I bought some honey). Government agriculture display and even an environment awareness booth. And of course, food and drink. We watched one of the alpaca beauty contests, when it rained. 
Ate roasted pig (lechon) and guinea pig (cuy, not much meat, tender, but skin was a bit tough. Same salty spice. s/20.) I think I prefer these rodents alive.In the afternoon, we visited the Cathedral (s/16, 1559-1669) . Nice carved choir, some paintings by the Cusco School, many dull chapels. The only thing interesting is a painting of Last Supper, where Jesus and his disciples feast on a guinea pig. Museo Inka (s/10), housed in the 17th century Palacio del Almirante, is well organized. Excellent guide. A hour-long history lesson of the pre-Inca Chimu, Mochica, Nasca, Pucara, Tiahuanaco and Wari people, and their influences to Inca, the Spanish conquest. There is a 3000 year-old funeral cloth, still in wonderful shape and vivid in color. A model of Queshwachaka bridge over Apurimac River, entirely made out of straws. Our guide emphasized the organization of Inca and their agriculture skills. According to her, these are the two crucial merits that enabled Inca to govern and expand, welcomed by various local tribes.
Went shopping at the Centro Artesanal Cusco off Ave. El Sol bordering Pachacutec. Bought more alpaca sweaters and scarves. More parades, well into the night. Ave El Sol was full of people and food stands. Drank a glass of hot soy-based sweet concoction. I liked it.
