Thank you I'm sure lots of people will benefit from that!! Using that tape is a great idea for finding the best location, I don't think I would have thought of that.
My average is 20.6 mph right now. I drive 48 miles to work one way, roughly 50% back roads, 30% highway and 20% city. That's not bad considering my car averages around 25 mph on the same trip.
And i drive over a pretty descent mountain range in the process.
