Sunday I saw someone drifting with their kite at W. The kite was inverted, it was a white liquid force havoc 10 or 12m kite. Not sure. It seemed with that wind direction (side shore) that this person was going to drift the length of the lake if no one assisted. I was the guy that got the kite back up in the air, and I saw you get back to the beach.
As I was riding l finally found your board, I think it was your board. It was a liquid force board, and black on the bottom. I brought it to the shoreline but it was about half the distance upwind to the jetty of where you landed the kite. Sorry but I didn't want to ride back downwind again. I tried waving to you.
Not sure if you found it, but I wanted to let you know that the board wasn't lost, it was on the beach. Hope you found it!
