OK. But what about the first day out when you might want to put on some real miles to go see some new territory?

You can't see anything when your going down the interstate so slow down and take the back roads and see what you have been missing. I start around 9:00 am and quit around 4:30 or 5:00pm. How far I get depends on what I do in that period of time. 71 years young for now but I might feel older tomarrow.
