We just had two weeks up around Crescent Head then Woolgoolga.
Hubby waved to literally everything(that he saw) with a green oval badge, from Defenders and Discos through to Sports and Freelanders.
He got a return wave about 5-10% of the time, and those were other Defenders plus a Disco or two.
The Defender's a tad hard to miss on the road. Maybe Land Rover drivers aren't losing the wave but are becoming more conscientious drivers and are concentrating only on the road in front? :angel:
