The last generation of farm boys grew up, got jobs in agri-banking or farm management and had kids who are in college studying accounting and the law. There ARE no more farm boys - which is one reason so many old farmers took up round baling, rather than square baling (of hay): no young men to help buck the square bales.
Rounds bails are cheaper to make than square.
Miss the old square bails though. Maybe miss bailing hay period.
