Take I-480 East to 271 North (you need to be on 271 North).  Get off at Mayfield Rd (towards Gates Mills - it says on the exit).  Keep going straight, cross 91.  Go up and down the hill, until you reach County Line Rd (traffic light).  Go left on County Line, the sign for the school will be on your right hand side.  Drive in the driveway until the first stop sign and go left - you will see the fields.
