I was just searching a soccer field/ baseball diamond ,,as you say ,,they overlap each other. I could not even imagine trying to grid a soccer field,,,scan might be a better word. I usually check the area in front of nets,,side lines and then just walk around the field aimlessly. But I guess it depends on the size of the field,,they are different.
The one I was on,,,was huge!!!
Here's a list of field sizes ,,by age!!!!
