Re: Float Tube Worries
In regards to moving yourself by kicking, its not hard, and its very natural. Once you are sitting down with fins on, you will instantly understand how it works and how easy it is. All you need to do is move your legs up and down, and the fins do the rest. As simple as that. As long as you have working knees, you'll be fine.
In regards to that turtle, we have plenty that size over here, and some even bigger. There's a small local pond by my house with a turtle that I can see from anywhere on the pond. Just below the surface, it looks like a small table is swimming around.
