This isn't what they are asking about. In 2014 zone boundaries were specifically described as the infinite plane extending upwards from the edge of each marked area on the carpet. This year's game manual says nothing about the 3rd dimension of field zones. OP's question is whether or not the air above the landfill/autozone is included as part of each respective zone, or if only the actual carpet is the real zone.
