When my brother was plowing. He had the contract for the local army reserve center. The contract was based on the amount of snow. 0 to 3", 3" to 8", 8" to 14". Then anything over 14", or something like that. I remember being 4 steps in the amount paid. It was a good contract because it paid well. My brother always hoped for over 14" of snow each time it snowed.
It would pay for the monthly truck payment.
