Castillo San Felipe del Morro, the fort that sits on the promontory overlooking the entrance to San Juan Harbor. The fort was one of my favorite places to go during my childhood in Puerto Rico. My college senior picture (in the Houghton College "Boulder") was taken of me sitting on the top level of El Morro. When I was in high school our National Honor Society did a walk-a-thon from our school to the top level of the fort. I can't remember now what the cause was. I do remember the exhaustion we were experiencing, walking all day. I think we walked about 12-15 miles. When we got to the road leading up the long slope to the fort, several of us felt a new energy, and we ran the last bit up the road and then up the long ramp inside the fort to the top level where a pile of cannonballs sits,and climbed it, too. It was exhilarating!
