The Ice Pilots series occasionally showed Buffalo Airways using frozen lake landing strips to make cargo deliveries with their DC-3s, C-46s, and Electras (NWT and Nunavut in Canada).
In serious winter (subzero temps) Ice houses appear all over for fishing, with half a dozen trucks parked around some of the larger ones.
Me, well, let's just say I have a phobia about being submerged below the ice in freezing water, in a vehicle to boot. I know it is fairly safe, and that the rare ones who do go through the ice do so because they were driving on it in warmer weather as a rule.
