But then, as I was taking apart the barbecue, I lifted the gas tank and I don't know if there is enough propane in the tank for a whole lot of cooking. So, early tomorrow morning, I'm going to get some. Fred Meyer has filled tanks where all you do is put down a deposit and pay for the gas, then when the tank is empty, you bring it back and swap it for another full tank! You don't buy the tank, you just rent it. That's a pretty cool idea. And I would assume that if you ever just bring back the tank, you can get your deposit back...maybe. It's just a guess. I'll find out in the morning.
