We joined another couple we had met on board and booked a day tour with a man at the dock. It started out very well - the 1st stop was to pick up a case of beer. It was going to be a good day. We spent the day touring around Mazatlan. There was nothing spectacular but it was a very pleasant day. We went through the market area and were amazed at the size of the shrimp - they were the size of hot dogs.
