I have never seen so many motorcycles with side cars in my life. Unfortunately many of them belch out horrible fumes. There are no pollution controls over here. They are usually a faded pink colour, and always crammed with people. On the highways we saw many an open truck crammed with workers, or children, and sometimes with people and bicycles stacked on.
Many people stand on the edges of the street corners trying to hitch a ride.
The local buses always seemed crammed full. Long lines of people waiting at bus stops were common. When we asked about using local buses to get into Havana, we were advised against it because of the frequent delays and overcrowding. We did the museum thing and saw several forts dating back to 1522 when the gold being routed to Havana was shipped out in convoys to Spain. Moro Castle was impressive in its size.
