That image reminded me of when I was working in Texas... wow, over a decade ago now. It took us 1/2 hour to convince the Texans that it was possible to drive a vehicle on the ice in the wintertime, but there was no way they were willing to believe that one could build a fire on the ice; that was just the Canadians trying to mess with them. It is true, though! Actually, up north they even use rivers as highways in the winter, although all of the truckers drive with one hand on the door handle or know exactly where it is, because even six feet of ice can be thin around an air pocket and entire rigs have been lost that way.
There's a fair amount of ice fishing here in the winter. Every year, there's at least one or two anxious fishermen who test the ice a bit early and have to have their vehicles lifted out of a pond or lake after attempting to drive on to thin ice.
