Parking is limited; consider using public transport.
Randall's Island Field #41 has restrooms available nearby.
The field is open year-round, but check for scheduled events.
I have been using it now for 3 months and it saves me so much research. Reduces the need to call and double check every time.
How did I not know these places existed?! Atly's scoring is a lifesaver, now I can finally find THE spot without wasting time Googling my life away.
