It used to be a Tennessee thing to have gun rack in the back window of pickup trucks. I am sure many of the pickups had their windows busted out and the guns stolen.
Back in the 70's and early 80's when there was lots of fj40's and 55's on the road we would always wave and flash the lights at each other when we passed. We always ignored the other 4wd's unless it was one of our buddies. These days....I don't ever pass another fj40.
