When I was in high school, our football team practiced on a fiel

Villas - When I was in high school, our football team practiced on a field next to the school that was fill dirt with a lot of stones and no grass. Our local high schools spend too much money to have nice, green grass for the teams. My high school produced a Heisman Trophy winner with fields of stone and no grass. What are we getting for the expensive athletic fields at our high schools?
