The Movie "lonely are the Brave" has a scene there the cowboy (Kirk Douglas)
on his horse is hit by a truck driven by Carroll O'Connor in one of his
first roles. The movie is a decent adoption of Edward Abbeys "Brave
Cowboy", another of his laments on the industrialization of the west.
By the way I saw that "The Monkey Wrench Gang" movie will be released this
year sometime.
