Thanks for the welcome Ray, I know what you mean about not needing a use for them in warmer weather as I am from Houston, TX and now live in Arizona! They are great for an injury, I suppose. When I go camping up north, they can come in handy as well. I will keep an eye out for the WalMart copies, thanks again.
