Sorry to hear about your wife's injury and this crazy experience. I wouldn't expect to find someone like this out in the wide open spaces -- you were in the Montana, Wyoming, Idaho region right? I'm sort of hot tempered when I'm provoked. I might have just used that big ol' Suburban to run that little Isuzu Trooper off the road, though I'm not saying this would be the best, mostprudent action to take. Maybe a 911 call right off the bat.
