Gorgeous weather. Somewhat breezy, but still sub-planing. Top speed: 9.7 mph. Only a few other people out on the water, including one speedboat towing a couple of women on what looked like an inflatable couch (see video). The temperature was 75F, but I still wore my shorty wetsuit and wasn't too hot.
This is Bill vdB, sharing little vignettes of windsurfing on Sayers Lake, in Howard PA. and sometimes elsewhere.
