I grew up in a small blue collar town where many of the small dairy farmers owned dump trucks that they used to haul gravel May thru October and plow snow on town or state contracts November thru April. That was back when towns would harvest gravel from stream beds during low water periods. They can't do that anymore, as it causes silt that impacts the Atlantic Salmon that have been attempted to be reintroduced in many New England river systems.
IIRC, a lot of those small dairy farmers also drove school bus routes and did other odd jobs to put make ends meet.
