There's the granddaddy of the genre, the Emmy-winning "Deadliest Catch"... There are more recent entries, like truTV's "Black Gold" (oil riggers) and Discovery's "Swords: Life on the Line" (New England fishermen), recently picked up for a second season. There's hardly a night of the week, mostly in the cable universe, without a men-in-peril show. And more are on the way, with another season of "Ice Road Truckers," the History Channel's highest-rated show, shooting now and spawning a second series that will follow truckers on some of the most hazardous roads around the world. "Ax Men," about loggers in the Pacific Northwest, will return in a few months, and there's plenty of "Verminators," "Storm Chasers," "Lobstermen," "Swamp Loggers," "The Detonators," and "Dirty Jobs" to keep the adrenaline flowing.
