I think they have some other things going on at the park so here are the notes from their facility manager:
Parking will be tight so carpool as much as possible.
Parking attendants will be present to help assist parking/traffic flow. Please follow their direction.
Overflow lot will be across the street (fields 14-16)
Do not park along Southshore Rd. next to the train tracks as it's a towaway zone.
Bathrooms located in the building and Portalets next to field 18
Sideline tents must be anchored at least 5 yard from the field.
Athletic Trainer will be under the tent in the middle of the annex.
