I can remember that from school, and all of the math and measurements laying out the field for the first time each season. When my kids played, some of the booster club dads gave the coaches a break and we lined the freshly cut field every Wednesday night (we called ourselves The Linemen). We used the spray cans instead of chalk, but the rolling dispenser was similar to a chalk dropper for the lines, and we had large stencils for yard line number we had to fill in by hand. Looking at my index finger now, I can still imagine that imprint of a spray can nozzle. It hung around a while.
They moved to sprint turf during my youngest's time, good to not have to worry about mowing and lining, but something is lost when you don't make a divot with your facemask.
