thin ice

There's a reason that officials set a deadline to get vehicles and shacks off of the ice.  They don't just randomly want to make your ice fishing fun come to an end. There's a very good reason for it; thin ice.  A couple in Manitoba found this out the hard way.  They tried to drive their vehicle across a frozen lake.  It would've saved them a couple hours on their trip but nothing is saved when the truck falls through the ice.  I'm not sure insurance even covers something like that.  Unless of course there's a stupidity clause in the policy.  sunken truck
