I've been driving my '79 CJ7 for twenty years now on and off the road. Years ago I carried a Holier Than Thou attitude toward many of the YJ and TJ Jeeps and their driver. I would wave, but only if they initiated. Perhaps driving Said classic and enduring all that encompasses ownership demands the respectful friendly wave of the oncoming "new guy/girl".
Today there are soooo many Wranglers on the road. I also drive a TJ on the street. So my.attitude has softened, and I will initiate a wave to oncoming Jeepers. Not everyone driving a newer Jeep is a Newbie! Most Jeep drivers ARE attentive enough to recognize a fellow driver and if not too busy, will acknowledge each other
I think a cool wave would be using the left thumb and first finger make an "L",, so your oncoming Jeepers will see it as a "J"!!!
How about it??? Could that be THE NEW THING !?!? A JEEP THING WE ALL WOULD UNDERSTAND
