SICC play at Walker Park on the corner of Bard Ave and Delafield Pl in Staten Island.
To get there by public transport:
Take the 1/9 train to south ferry (last stop).
The ferry to Staten Island leaves on the hour and 1/2 hour until 8pm on the weekends, from when it only leaves on the hour.
On Staten Island take the S40 bus down Richmond avenue. get off at just before the Getty Station (~5 mins). This is the corner of Bard and Richmond. (you can do this step by taxi, it costs ~$4, and is quicker than waiting for a bus on Sundays)
Walk one block inland, to the corner of Bard and Delafield Pl. You are now at Walker Park. If you come by car, you cannot drive down Bard, as it is one way. You must take Davis Ave, which is the next street when traveling south along Richmond.
