Hard to find but otherwise very convenient. Located just outside the hospital building, but not near any entrances. Drop box is at the north corner of Laurel & Central, on the sidewalk, right next to the ticket dispenser for the parking garage

I found this dropbox, but the address listed is incorrect. It's 1402 S. Central. If you walk up the driveway where the entrance to the parking is, it's well hidden on the left. It's outside on the side of the hospital.
