Seeing a big yellow stump grinder on wheels in the yard behind us this morning reminded me of what I saw last week:
In Marietta, on Fairground Street near the corner of Roswell Street was a big yellow machine on wheels doing some roadside work. It may have been smoothing out some freshly laid asphalt or something else, I don't know what it was doing, but it was doing something.
However, no human was on it was controlling it.. The human was nearby, maybe fifteen feet, operating the machine by a little remote gadget.
That is one of those "Yee Doggie! What will think of next?"
