Toddy,
Honey bees do not go feral here, they do swarm if they get ahead of their keeper of course, but they can't make the winter through. Everything has been tried, and other than moving them to a warmer place for winter, they always die. I enjoy the honey, and the keeping of bees, but here there is a sadness to the whole affair, this business of buy them, let them work, rob them, and let them die. Of course, I buy pigs sometimes too, keep them until they "must sit down to eat their last bushel of barley" and then make pork of them, but it isn't like simply letting them starve after I've gotten the pork, as it were.
I've a brother, who lives several hundreds of miles south of me, and he keeps bees. The temptation is to truck them the thousand miles to his house to winter over, but his land is covered with his own bees. So, I buy bees every few years, and then can't do it again for several years.
