Lol! Us "Portly" guys are fortunate to have "Svelth" buddies around at times like that! Not that you're "Portly" anymore Skip, but I know you used to be heavy & it sure takes a toll on the ol knees! What's worse is when you can't get down on your knees & you have trouble standing up cuz of your knees! Wish they'd come up with an affordable "Personal Hovercraft"! LOL!
