that afterwards, while doing barn chores, i started questioning myself and the decision to report this asshat, but your posts reassure me that i made the right decision.
so anyone w/ a police connection know how long this ‘complaint’ will remain lodged with the police? is that something that clears out of their system within the next few hours or does it remain in there for a long time? i’m just curious whether it’s possible that they stop this guy 3 weeks from now.[/QUOTE]
No question; your report was the right thing to do, especially if that moron gets involved in an accident on down the road somewhere. Don’t know how long the info stays in the system though.
DH and I had a tailgater in very much the same type of situation. Speed limit of 45, which is what we were doing. Speedy Gonzales in a shiny new Mustang roars up behind us and nearly sits on our trailer bumper. A bit of a straight stretch comes up (still double yellow though), and he races on by. I say to DH, “Man, where are the cops when you need 'em?!”
Lo and behold, about a mile further on down the road, we see it. Flashing blue lights of a state cop car, and the officer writing up Mr. Speedy Mustang. If there had been a suitable shoulder to safely pull off on, we’d have done so and given that cop a bit more info about Speedy. 
As for getting irate with other drivers, I abstain from it openly, especially when hauling my horses. Way too many nutzos out there behind the wheel.
