Bob,
It was about 20 miles or so east of Gunnison and the owner of the finger was a Texan inna Tahoe. I think he might have been primed by being cut off by a dude on a bike that mounted two sets of elk antlers (fore and aft), and a grizzly bear head "sissy bar" that had come through earlier. We were all stuck behind a huge hunk of oil field gear, goin' slow, so when I popped around him and we all had to stop, he wanted to "chat". I just told him "thank you very much" (or something that sounded like that), and boogied on.
