Here in Indiana, you get either get a wave or not depending on the "class" of the Jeeper. The "built", modded, or "old school CJ" guys wave at each other, but as your rig gets newer, then you apparently are less obligated to wave. I was sitting a a stoplight a while back, when a mom and her daughter rolled up. She was is a new 4-door, I in my old, rusty, lifted, home-built bumpered, D.I.Y. "Heep", and she, forgetting her top was down, commented to her daughter what a piece of crap mine was. I just waved, smiled, and rolled on knowing that mine was more capable, and will at least see some trails/dirt. I think for some of us, it's a life-style and hobby, for others, "It's a Jeep Thing", and apparently WE will never understand.
