You may have been alone at BWB, but you weren't alone on the lake. I had a short but pleasant session on my biggest stuff (9.5m sail, kids formula board) down at Chucktown; saw you up at BWB and headed for shore pronto when your kite disappeared from view. As you say, because of the sunshine, it didn't feel too cold, although by the end of the session (about 4:30 in my case) the air temp above the water was about 42ºF, water temp about 46ºF.
