If you wonder if a Bear cares about hygiene, this might help you. I live in CA and have been to Lake Tahoe more times than I care to count. I got married at the lake to my last wife. But first about the lake. If a person cares to get into frigid water, that is your lake. Where the sand is and where the water is shallow, at least the Sun can warm that water up a bit. I recall laying in the sand one time with a then girl friend and next to us was some European woman, (I presumed) topless. I do not enjoy cold water swims and my girl friend did not really like the cold water either. It was a very warm day and we did enjoy the beach. When you watch the video, notice the people are on top of floating things. It takes a real snow dude to stay in that water. http://www.sfgate.com/science/article/As-with-lakes-around-world-water-temperature-in-6767527.php [video]http://www.aol.com/article/2016/08/04/lifes-a-beach-mama-bear-and-her-2-cubs-spotted-splashing-in-wa/21445221/?cps=gravity_4816_-6168382822007644024[/video]
