It's a drag-and-drop operation. As noted above, I already shifted the city for the year.

This note remains active as the city may shift a couple feet again in a week or two. The shift is unlikely to be interesting to most people; perhaps only to folks using the city layout to plot their camp layout. For example, Alternative Energy Zone plans their village/camp layout ahead of time and programs a 4ft wide robot to physically auto-plow the lines into the ground based on GPS traces.
