Don, Sounds like the "radio guy" must not have known for himself! At first, someone might think it was for something complicated, but Tony's description is all there is to it. I have had to explain why we have nitrogen many times here at the TV station, usually when I am filling up someone's flat tire with Nitrogen (because we have that, but don't have an air compressor) It usually scares them at first... Everyone asks "Will my tires explode?!" and I say Nitrogen, not NITROUS!
