A long caravan of vehicles carrying families drove around Good Samaritan Hospital in West Islip around 6 p.m.
Drivers honked while passengers held out signs of thanks, with one truck even carrying a huge billboard.
The caravan was so long, the line looped around the hospital's parking lot as dozens of nurses, doctors and other staff came outside to watch the appreciation parade.
Some even fought back tears for the emotional show of support.
