From the south:
I-675 north until it ends (just north of I-70)
Road becomes Rt 571
Stay on 571 – at one point it comes to a T intersection, 571 continues to the left – through New Carlisle.
There will be a grain elevator on the left. The field is just past that. Park across the street for weekday games. The lot beside the field is fine for Sundays.
From the north or west:
I-70 to Rt 235. Take 235 north to intersection with Rt 571 (downtown New Carlisle).
Turn left on 571, and follow the directions above.
