I don't mean to highjack your thread! Just consider it a slight diversion!
I just had the propane truck stop by today and check our 300-gallon tank out behind the house. He said I was only down to 35% capacity and he was going to leave it alone. I told him I'd rather have more in the tank then that and he said "nope, no way" and said that they're rationing their propane because they can't get any at the moment and are almost out! This is Suburban Propane; not exactly a Mom & Pop operation!
I tell you, it's enough to drive a person nuts sometimes!
