We travel for business so we try to make about 350 miles per day at 70 MPH. However, we had some issues with our coach recently and to get where we were going we could not exceed 60 MPH for very long without causing issues. We had to get there and doing 60 got us there. Here's the point......Driving 60 MPH was super relaxing and we actually enjoyed it. We enjoyed it so much that we did nearly 500 miles one day just to get ourselves back on schedule to keep our boss happy. I now really understand the concept of taking your time and smelling the roses. We may never do 70 again when the 60-65 MPH range was so easy. The only thing I didn't like was the number of times I flashed my headlights to let the 18 wheeler passing us that it was OK to change lanes....Whew!
