Our building is in Harbor Island Park in Mamaroneck, and we don't have a street address that you can plug into your GPS. However, you can use this address to navigate to the entrance of Harbor Island Park: 

111 E Boston Post Rd,

Mamaroneck, NY 10543
  

After entering the park, you will encounter your first stop sign at the ticket booth. Proceed to the second stop sign beside the large ship's anchor and turn right. Follow this road with the tennis courts on your left and ball fields to your right until it ends in a parking lot. There are four buildings along the water's edge. We are in the second building from the right. There is a Coast Guard Auxiliary sign on the building.
