Way over on the right hand side of the picture is the electric fencer. Ours runs off a battery. Two years ago, we have two hives destroyed by a bear so now we take precautions. Installing new bee hives is not an inexpensive hobby to have so we like to protect our investment as much as possible.
It wasn't even 30 minutes after we had the new bees installed when we saw a bear walking up our property line on the backside of the barn. Luckily the bees are on the other side of the property. The Farmer followed behind the bear to see where he went but lost track of him (from like a distance of half a mile!). Fortunately, we haven't seen the bear since. And being the good blogger that I am, I scolded the Farmer for not taking the camera. He gave me the "you're nuts" look. So I gave him the same look because hey, I'm not the one that was following a bear! :)
