The ruler makes me think of baseball fields and how far each fence on each field is. There is all kinds of different distances of fields like one field could be 100 ft and the field next to it could be 400 ft it all depends on what age groupe plays on the field like 11U would play on fields like 200 ft and 12U would play on fields that are like 250ft and 13U would play on fields that are like 300-325 ft and 14U and up would play on like fields 325-400ft.
