re: Are dash cams worthwhile?

Visiting Arches NP one time, I decided to record the trip out of the park with a gopro stuck on the windshield. In one of the curves a Class A slapped mirrors. I couldn't turn around and pulled up at the park headquarters, the guy already was calling saying i crossed the line and hit and ran. A single frame grab of his tires across the line shut that down pronto. Saved a ton of headaches at the time.

So here I am a few years later and I still don't have a dedicated dash cam.
