Rick ... I can match your car story. One hundred years ago, when I worked at a previous job, we had a boss who spent weeks researching a possible car purchase, based on the best possible mileage. This was during the NIXON gas wars. He got his new car and started parking it in the employee parking lot. We all started adding a little gas, now and then. But we all did it individually, we didn't know that anyone was doing it except ourselves. "Gerry" started getting gas mileage readings like 20, 30, 40, 50 ,56 miles to the gallon!. When we realized that we ALL were doing the same thing, we all stopped at the same time. His mileage plunged back into the teens. Jerry hollered on the dealer and took the car back. We all had to share the burden of driving "Jerry" to work and back to home. One of things I've always appreciated about "Jerry", he was a very good man, was that after the story came out, he bought us all a beer. True story. CHEERS, Bob
