I would like to add that it can become a problem. One of the recommendations I make, to encourage Canadian self-sufficiency, is to simplify trade in queen bees and nucleus colonies between provinces. However, when you are transporting bees from one province to another, it takes longer than 12 hours and you are facing exactly the problem you describe.
It is important that we offer support in this situation. We have to get from point A to point B to unload the hives. We can't do it in the parking lot of a motel.
