Jim beaver (Supernatural's Bobby Singer) starrs as Vietnam Joe, a war veteran who "spends most days smoking pot at his camp by the Tijuana Sloughs and fishing off the Imperial Beach pier. He occasionally ferries illegal immigrants into town in his van – when his militaristic manner doesn't send them running." Source.
