Click on the first photo below for 110 seconds of video I shot of an up-and-coming windsurfer on Lac Bay. He's probably a local because of his skill level (although nothing like the pros - yet) and the fact that he's not on rental gear. The footage is interesting also because it shows the massive surf just outside the reef and the overweight cruise-ship people in the foreground. Click on the others to enlarge them and see captions if any.
This is Bill vdB, sharing little vignettes of windsurfing on Sayers Lake, in Howard PA. and sometimes elsewhere.
