I used to watch a show called Ice Road Truckers which was pretty cool - It's a different world from Australia really, all that snow and ice. It's funny as here we have signs in outback towns, right before the bitumen starts, that says drop dust here, a point where the road trains, sometimes 5 trailers long, stop and smack the shit out of their trailers to knock the bulk or dust and mud off before they enter the town so as not to drop it through the town. [These road trains often run for thousands of kilometres on dirt, through creeks and mud and all.]
Anyway, I feel better now I know you'll not let me fall through the ice and drift away downstream under the ice.
