It is frustrating to drive around waving all day and have so many waves not returned. I subscribe to a couple of forums and have read several different threads about the Jeep wave. I have read many different opinions, TJ, YJ, vs. JK. I've heard people talk about not returning a wave if it comes from a JK or a four door. I just bought a 2011 JKU. It is my first Jeep in twenty years. I really miss my old CJ. Just my .02 but a Jeep is a Jeep. I wave at a Wrangler be it TJ, YJ, CJ, or JK. My wife gets a chuckle out of it every time I tell her "It's a Jeep thing. "
