@pane, I'm not sure of anything! I took notes when I called the gas supplier a couple months ago and my notes say he told me the tank was 20 lb. So I guess I'll just have to wait and see. But if this stupid COPD progresses any worse, I may be out of luck with N2. BTW, I am such a total fan of black cats (had to euthanize my elderly black cat several years ago), so every time I see your avatar, I get all purry.
