It's like bigfoot here too...not all that common. The few that are most likely to give a wave are the ones that are also on the outskirts of the Jeep family. The Comanches, the YJs, or other older jeeps (FS or other pre-chryco). Eagles as well. I've had a few XJs or TJs and like give waves, but it's the exception and not the rule. And they clearly are only waving because they recognize that it IS a Jeep. Most don't have a clue what we have ARE Jeeps.
I just try to take note of any waves....whether they are using all their fingers or not. That says a lot more about people.
