Roy makes it sound like we travel a straight-forward path, but in fact we often make wrong turns, or miss a turn. Had we not done so, yesterday we would have missed seeing this bridge, which we crossed twice.
We also reroute to go through towns because they are more likely to have convenience stores or cafes with restrooms. We can often find them because of their water towers.
Sometimes the town centers are especially charming, like this town square in Bourbon, Indiana.
This helps explain how we accumulate more miles than the actual distance between towns.
