During the low season, year-round residents will notice that the city is a substantially quieter place to live.

It is a fairly quiet town because there are relatively few of those groups of people who have a tendency to be noisy. (Children, for example, often can't help themselves from being noisy, and being parents ourselves, we know!) Arnold has relatively few families with children living at home, and is quieter because of it. Renters and college students, for their own reasons, can also be noisy. Arnold has few renters and college students. But the biggest reason it is quieter in Arnold than in most places in America, is that there are just simply fewer people living here.
