DRIVING ON ICE

In many northern states the winters are so cold that the lakes freeze right over. In Minnesota, Michigan, and Maine, the ice in these lakes can freeze two to three feet deep.
When the ice is that thick it becomes possible to actually drive a car or truck across the ice. While driving on ice sounds like something that people would do just for fun, a lot of people drive across frozen lakes for very practical reasons.

For example, there are people who live year-round on islands within these northern lakes. In the middle of winter the only practical way of traveling to the mainland is by driving across the frozen lakes.

Actually, when the lake is frozen two to three feet deep, this is a perfect opportunity for people living on islands to transport large objects onto or off the islands. Say, for instance, you owned a cabin on a small island in the middle of a lake in Michigan. Suppose you decided that you wanted to build an extra room onto the cabin.
