I was watching t.v. last sunday night I came across a really good show called "ICE ROAD TRUCKERS" it was a bunch of drivers wayyy up north in Canada and the have to drive across frozen lakes to get to the new diamond minds they found up there, it's crazy. they show you how trucks fall in the lake, and how they get them out. And all of the other good stuff that goes with it. also the tempture up there is -40 degrees farhenhite it was on the HISTORY chanl. I think at like 7pm check your local listing Ithink you will enjoy the program
