Excuse me for sticking my nose in here, I found this picture on Wikipedia, and it says they "plow the road for Main Street". From what I can see, it is not winter. So, it is not snow plowing. What are they actually doing in that picture ?
Early roads made from cobblestone were first plowed using horse-drawn plows so that the base could be softened up and leveled before the cobblestones were laid down by hand.
