Cuba is in many ways a strange country. It has two currencies in circulation. The sparse traffic is made of rickshaws, horse carriages, ancient motorcycles with sidecars, and flamboyant Buicks, Chevys and Fords from the 1950s, many of which have surely just left the showroom via a time machine. Here, a doctor or an engineer makes about as much money as a construction worker or a street musician. If you live here, Internet access is tightly controlled and prohibitively expensive, but gender reassignment surgery is free. Strangest of all for these hyper-consumerist times &mdash and it&rsquos the first thing I notice on landing in Havana &mdash there is no advertising anywhere. Not on the sides of the jet bridge, not in the airport, not alongside the wide roads leading into the city.
