Your mention of farm work in the Pacific Northwest brought back memories. Back in the Dark Ages when I was growing up in Oregon, and later in Idaho, I would catch a bus in the morning that took me and the other juvenile conscripts out to the fields and brought us back in the late afternoon. After a summer spent picking strawberries any job is easy. Before the Santa Clara Valley got overrun with houses and became Silicon Valley, a lot of kids spent their summers cutting apricots and picking fruit. Nowadays that would be considered unacceptable child labor.
Personally, I think we need to bring back that "unacceptable" child labor. It definitely motivated everyone to finish high school and go to trade school or college or start a business. Planting trees for reforesting and working Christmas tree farms wasn't a lot of fun, either. We used to have these little seedlings in plastic tubes (how un-environmental) that we shoved into the ground with an applicator and the plastic tube either broke or was removed, depending on the system.
