My current favorite games is "what if..." What if I still had the Sport Trac? I decided to get gas this afternoon (should have done it this morning when it was 6 cents less) so I took in 5.8 for $19.50. Based on mileage I like to calculate what it would have cost if I still had the 14mpg ST.....$62!!! I can't even begin to figure out the savings of time as well as mere mpg!! I also like to see how many Prius I run across on my travels, Do I see them on a daily basis (yes!!) There are so many numbers games you can come up with.....
