I admire you kewl if you can drive 100 miles at 55mph. I think I might go nuts if I had to do that. I will have to check my milage sometime. My wife and I cruised down to the Oceanfront in Virginia beach Sunday for lunch. At one point she got annoyed and said how fast are you going? I looked down and said, just about 100. She said well that is too fast, slow down a little so I dropped down to 80 or so. How can I expect good gas milage when it is just so much fun to "get on it" a little? I figure so what, I don't spend a lot on movies, I'd rather run the Interstates.
