Interesting to watch this discussion.
Seam in a road. Where we live, there is usually a road crew with signs, trucks, people, etc and you can’t see much of what they are doing. This should work on the layout. Road is under repair and hides the seam. Remove/reassemble in 5 minutes.
Or you could stage an accident, flat tire, etc.
One unrelated question. The floodlight tower… is it LED or the old burn out every hour style bulb? If no LED, don’t forget to convert it while you can easily do so.
