Don't have to worry about ski boats and jet skis running over you this time of year.
Funny you say that when I looked in the post #3 first picture I thought I seen a skier towards the shoreline left side of the picture.. looked to be a slalom skier.
Then i focused and it was the line guide on the guys fishing rod..I was thinking FOOL is out playing in the water.
I have been out this time of year Very cold water Diving off the cliffs at tenkiller and swimming to the other cliffs 200 feet away and diving in off that side and back and forth.
