As always I lisen to your podcast Monday afternoon. Which is probably why I get nothing done and may be asking Ray for a job soon. However, This week's episode struck me personally. When Helen called in about her MPG gain. I knew right away your answer was incorrect! B-o-o-o-o-o gus! No stump the chump for you! You see, in 1999 I moved from Hilton Head Island South Carolina to Tucson Arizona. Then in 2006 I moved to Eau Claire WI. All with the same vehicle. My prized 1991 Ford Taurus SHO Plus! I noticed an increase in my MPGs as well when I moved to Tucson and a decrease when I moved to Wisconsin. I believe it has more to do with air density than any other factor. Very humid air is denser. This creates more drag. Imagine swinging your hand in a pool and then out of one. Now imagine that at 70 MPH. HHI was a very humid place. Wisconsin is either humid or snowing. I am sure other factors could apply as well but over a year or so, those factors would go away (tire pressure, Computers, driving habits etc...) So long story short I would bet a 62" plasma TV with an authentic Donald Trump hair flip I am correct! Take that! Ha!!
