Thankfully, kids don't just like to veg out in front of the tube, they also enjoy speeding around on a tube in the middle of a lake. In the top photo we have Robbie on the tube with Ryan hanging onto the back right and while you can barely make him out, Josh is holding onto the back left. The second image has Robbie at the helm of the chariot, raring to go. After a few runs the tube slowly started deflating.
On this day I was in one of the kayaks taking pictures of the boys tubing. On the second day I actually went out on the boat and gave it a try myself. It was a blast and more exhausting than I imagined.
