I've never been to Cuba, but your pictures remind me of Peru. Old world Spanish colonial architecture mixed in with obsolete "modern" technology, like the cars (from the 50's and 60's), electric/telephone wires strung haphazardly across streets and buildings, yet the streets are crowded with people talking and texting on the latest smart phones. It's a strange mix of old and new world, poverty and wealth, clean but dilapidated, all at the same time.
It's like being in Disneyland, visiting a particular theme area where it almost looks like the structures and the costumes are fake...but it's real world stuff.
Hopefully I'll make it to Cuba one day to see for myself. Thanks for posting...cool stuff!
