A wind-surfer was having a "rush" of a time..just before sunset. Can't see him very close..but he was just whoopin and hollerin..having the time of his life!
Good picture! I also think that the sky is beautiful. However, like you said, it is kind of difficult to tell that there is a person windsurfing... maybe the picture would have been better if the windsurfer was either more visible or out of the picture completely.
