I arrived at the Garden City DO at approximately 10:15 this morning. My interview was scheduled for 11:25, so I decided to try my luck and see if the security guards would allow me to get in early. They politely told me to come back at 11:00, so I dropped my fiancee off at Bloomingdale's at the Roosevelt Field Mall and drove back to the parking lot at 711 Stewart Avenue. I should mention that there is plenty of free parking available, so don't worry about where you can leave your vehicle.
