Hi, I was on the beach in Ocean Park Park on the beach today (between Isle Verde and Condado, near Barbosa Park, and a lot of people were parasailing and sail-surfing (?), so I walked down and saw that they were giving lessons. Today was very windy and a lot of people were out doing it, so I suggest checking into that. I couldn't see the business name, but there was a .com. there may be one near you or this is a short distance. I photograph them ;-)!
Also, Que Pasa Magazine which you can pick up at most hotels has some good ideas. I've found that CL, which I was used to using, isn't that active here. I haven't found a very active forum for connecting with people who want to join in activities yet. If I do, I will certainly post here.
