That's funny, I was just going to say around my area there are a lot of Jeeps driven by young girls that were bought for them by Daddy. They have no idea about the "wave".My buds wife used their daughters JK 4 door while her car was in the shop. Her daughter said dont forget the "jeep wave". Her mom said what's a jeep wave? It was explained and she said "I'm not doing that to every jeep I see!!". The daughter was pissed! lol
After telling me the story they asked if I do it to every jeep. I answered yes out of habit, but I never look to see if I get a wave back. I really dont care honestly. I get why many dont do it. There are so many out there now it's one big stadium wave after even a short jaunt.
Your buds daughter renews my faith that the 'wave' may just live on through the younger generations.
