To the Church of Christ at Greenpoint
The Church is in a residential area, and parking is limited. You are advised to use mass transit if at all possible. Otherwise, you may spend half the morning or evening looking for a parking space (seriously).
Basically, the Church is located on North Henry St. in Greenpoint, (northwest corner of Brooklyn, just south of Long Island City, Queens)  between Nassau and Norman Aves. (closer to Nassau),  6 blocks east of McGuiness Blvd., west side of street. It is in the block just north of Monsignor McGolrick Park.

The Church is about nine blocks, overall, from the Nassau Ave. station of the G subway line. You can get the G easily on weekends and late evenings - the trains run frequently.
