We went to the lake one day and rode on our friend's boat.They had a big tube that you can tie to the back of the boat. So, my family and a couple other families got to go in the tube. In between every turn, we all jumped off the side of the bout and swam around a bit. It was really fun, but as you can see in the two photos, I had to wear a big life-jacket that was pulling me up while I was trying to go down. It wasn't very comfortable.
