When out in our motor home, my husband and I like nothing better than to wave to other motor homers! A few years back we noticed someone waving to us (from the otherside of the carriage way) with a yellow hand, which I thought was brilliant. Since then I have been looking for one, especially at the shows we have been to with out success. Can anyone put light to this question, where I can get one from as I am getting RSM from all the waving I am doing!!! May be it was a DIY model and if so then should get a patent for it as I think it is brill and would certainly buy a few to use in my vechicle!!!
