From Santa Clara to Havana was our longest road day, 293 km. We were on the main highway, and the land was flat, with bushes and scattered trees. Daniel generously endured my many questions; I had been sitting across the aisle from him for the whole trip. This time I learned that the mimosa bushes are invasive, but not the mimosa trees. Thus, the bushes are burnt at the roadside to kill them, and the trees are planted for shade, for example, in coffee plantations. I tried to make a list of all the different models of cars, prompted by the sight of a modern Lada, a make that used to be (maybe still is) the butt of many Russian jokes. What I learned is that many cars dont have any indication of make or model, particularly the classic cars. Of those that had symbols, I failed to recognize any but the most obvious, such as Plymouth and Hyundai.
