Who is BS'ing who?

When I put gas in one of the older cars available here, I don't measure my mileage in MPG, it's measured in SPG...smiles per gallon. I don't know what I get in any car to tell you the truth, I just put the gas in and go, when it's out I put more in. I know about how much $$ to bring or put in to get there and thats about all the thought I put into that subject!! Just enjoy the ride while you're in it...you could be driving a mini car soon enough!!! Geof
