I've been wondering what is everybody else is doing? Are just letting the Bottle roll around on its own or maybe a towel or block to chock it. What keeping it from getting damaged? Is any using some kind of bottle bag, caddy or cart? My wife took one look at the bottle and said you need to go down to medical thrift store and buy one of those oxygen bottle hand carts! It didn't sound too bad, after carrying every thing out to the back yard for a after noon of plinking takes a minute. I like to hear and see your ideas. Thanks Monte
