Thanks -- the truck unfortunately does not have rear tags. It does not help that this area is near a prison (!). Sounds like the 60+ honker is buddies with the confederate truck guy. And to think I was just defending people from my girlfriend's criticism of rebel flag wavers recently...this one sure fits the stereotype she laid out though.
I am also thinking about hanging a small can of mace from my jersey - I saw enough wheel chasing dogs tonight...
