Coordinated mowing

When we came back into the neighborhood where our Airbnb is in Juneau it seemed like everyone was out with their power yard tools: one woman was mowing, the guy across the street was using a chainsaw on some branches, somebody down the block was doing something else. It was as if they had decided to coordinate the time for using noisy stuff in the yard. If they hadn't, still, it's really the most brilliant idea ever to do so. An extension or corollary of the widely accepted practice that one does not mow on Sunday morning.
