It seemed silly to visit Puerto Rico and not visit the radio telescope at Arecibo so we drove over for a look about. Turns out that the telescope is sited in a region of karst south of the town of Arecibo. As you might imagine, there are no primary roads from the expressway south, so we wound about for a long time on very narrow roads never sure that we actually getting anywhere until we finally popped out right at the entrance.
