If you watch the two little kids are both seated next to Jon in the FRONT of the boat and Cara was in the back on her knee's facing forward.
I did notice that ~ and immediately thought that it was an unsafe thing to do. Mostly Cara up on her knees facing forward. It just didn't seem like a good idea. Now I know, the likelihood of an accident in a paddle boat is probably small .. and maybe this is just me, but I always err on the side of caution when I'm in a boat. You just never know what can happen.
