No question that propane is getting way to expensive. Kerosene is the same way -I have a kerosene heater for emergencies like when the power goes out in winter and it's getting too expensive to run. Kerosene is around $10.00 a gallon and it used to be real cheap a few years ago. Much of that increase is due to federal regulations and the EPA along with the Obama administration that is anti- oil, gas and coal. I have no propane grill but I do know a full tank of propane that is used on fork lifts weighs around 75 pounds.
Forklifts - the most common tank is a 33.5 lb tank and full weighs almost 60 lbs. (On the forklifts I have driven the most...)
And no, the price has not run up under Obama - it has actually gone down just a little for any quantity more than the 20 lb grill tanks. Just like gasoline costs so much more under Obama....oh, wait....what?
