No Virginia, those are not surfers looking for a gnarley wave in the East River passing Roosevelt Island. They are surfers paddling for charity today circling Manhattan. Go to their website to learn more.
If anyone shoots pics of the paddlers today and sends them to RooseveltIsland360@gmail.com I will post them here. Make sure to include recognizable Island points of interest in the foreground or at least Manhattan views we recognize in the background (i.e. the Queensboro Bridge etc).
