MPG Reality Check
I interpret what Al is saying is that he can afford "it" and so he doesn't worry
about mpg. He has a point. Certainly, worry isn't going to get a fellow any better fuel economy. That being said there are folks who have to consider each and ever trip and the costs involved, it's a fact of life. How many of us are on what side of this bell curve I have no idea but I would guess there are darned few who wouldn't appreciate an improvement of one or even a half a mpg. I know I would. So this discussion seems relevant to me. While shopping for bus I ask a PO what the fuel usage was. His comment was if you have to ask you can't afford it. You know I didn't buy that bus, and I am not too certain that comment wasn't the biggest reason. I am only making an assumption of what Al meant by his comments. And I take no offense either. It is what it is for each of us. I am not without but I must admit that filling the tank causes me to wince. Some would wince regardless of their financial circumstances. Some of the wealthiest people I know would complain the loudest. And on the other hand I wonder some times how I will finance this as time goes on. For the time being I am with Al enjoy it because time is what is most fleeting. I am grateful that I can "play" and pay to play but I also do not take a bit of this as a given. Not sure that I added a thing to this conversation but I had to comment. --- In WanderlodgeForum@yahoogroups.com, "Chuck Wheeler" > > I agree with you Al.
