That is what scares me, don't get me wrong, I am far from being in a wheel chair and i am in good shape but my balance is not as good as what i would like. I have the bad knee ( ankle ) and I have also had a bout with vertigo a couple of years ago, i think I am about 90 % back to normal from that ordeal. I occasionally fish out of an alweld jet boat and have not fell out of it yet, it can be pretty tippy, maybe I can get Adam to let me jump in his boat to check it out, may have to check his waypoints out while i am in there,
