On Monday, 2 huge boxes (tire + rim) are attempted at apartment, no one home NI1. Tuesday, the other 2 join them so now 4 huge tires, no one home, 2 NI1 + 2 NI2. Wednesday, no one home again so now 2 NI3 + 2 NI2. What do you do when you get in ? Luckily, the 4 boxes were SDWC an hour before I got back to the building. It's that gray line between procedure and common sense that keeps the best drivers guessing everyday.
