I have to say that I don't like many of the Discovery Channel shows, because they are so much staged and you can see and feel it. This show however feels somehow real and the main characters are likable guys, doing their exhausting work in the bad conditions of Canadian mountains. If you like cars and trucks this is a show for you, in my country we don't have such though conditions so we don't have such high-tech towing companies as Jamie Davis has. I watched every episode with great interest, you can see amazing performance by the towing crew. Jamie himself is a great character and great boss too, who tries to solve problems with his employees in a good and fair way, you have to admire him.
I love the last episodes of every season, where they meet at a table, drinking beer and summarize the whole season. It gives the show another perspective and deepness.
Overall a great show about huge trucks in the ditches of the CCHL Highway, combined with great team of people and interesting problems to solve.
Thanks Discovery :)
