You do not see milestones on modern highways. In the US they have been replaced by green, metal markers that number the miles you have traveled. Of course modern vehicles have odometers counting away those miles, distance and years put behind us in the many little journeys of life. Back and forth to work, around the island, daily routine and explorations. In a good life those miles represent both the mundane and little adventures.
I put well over 200,000 miles on my last vehicle. The new vehicle? Purchased with 78,000 miles already on the odometer, thus I can only claim the last 22,000 as mine alone. But this was a Keck fleet vehicle, I put a smattering of the previous 78,000 miles on this truck, either driving or riding up and down the mountain.
