On the morning we docked at the Canary Island of Tenerife, Dr. Blake and I hopped on a spiffy new tramvia and rode 45 minutes up into the mountains to the beautifully restored city of San Cristóbal de la Laguna. With its narrow streets and vibrant colors, it reminded me of parts of Havana. And I said as much to a nice woman in the tourist office where we’d gone to get a map. She teasingly corrected me, saying, “La Laguna does not look like Havana. Havana looks like La Laguna.” So noted.
