Cam Edwards tells a frightening story about a man in Houston, Texas, who was randomly shot at on Interstate 45. The man was driving his pick-up truck when a Pontiac Grand Prix pulled up next to him with four men inside. The men began to shoot at the truck driver, then pulled off the road. The truck driver pulled onto an overpass and retrieved the rifle from his vehicle to defend himself when the Pontiac returned for round two. The truck driver fired this time, killing one of his attackers and wounding two others. That's today's Hero of the Day.
