The tie up at this cabin would be good most of the time in the summer, the problem is there is no close place to hide if the wind comes up. Because of the tie up situation overnight at this location may be a problem. The best cabin for overnight stays on this lake is the Pipe Creek Cabin which has a safe place to get the plane out of the weather.
