Ice Road Truckers is one of the most harrowing of the "dirty jobs" sub-genre of reality TV. This History Channel series mines a little extra drama by playing up the competition between the drivers to see who can make the most runs. The series' most compelling personality is Hugh, a 21-season veteran known as "the Polar Bear," who suffers what another driver calls "a bad luck year." Hugh is the kind of guy who will blow poisonous methyl hydrate into his own suspect transmission. Among those trucking for him are Alex, the 25-year "marathon man" with 11 kids), 21-year-old TJ, and Drew, a 35-year-old "newbie." But the conditions under which these "titans of the ice" operate is all the drama this series needs. Suffice to say, there are up to 800 drivers when the season begins. By the spring thaw, there are only about 125 remaining. Consider: Truck breakdowns and equipment failures can leave truckers stranded in the middle of nowhere in 40-below temperatures. Blinding snowstorms can reduce visibility to zero. Speeding can cause waves that blow out the ice. A shout-out to the camera crew who faced these dangers with the truckers and captured nerve-wracking footage of the trucks making their treacherous way over heaving, cracking ice, and behemoth 18-wheel rigs plummeting through the broken ice to the lake's bottom. --Donald Liebenson
