Since I can't post a URL, go to The Weather Channel and search under Video for "Sochi" and you will see a clip titled "these-can-survive-sochi-climate-44199"
Interesting video clip on The Weather Channel. They are saying these Caucasian bees are rare....
The hives are unique as well. In the background you can see a fella removing a frame from a horizontal hive.
It would be interesting to hear comments from the beekeeping community.
