http://bearspray.com We baited the bears with bacon to test the fence for approval by the Forest Service. We smeared half cooked bacon and left full strips of bacon only 4 inches inside the fence. We filmed the bears for 90 min. One bear only would touch the fence. They can sense the electricity. The Forest Service is continuing to test our fence and it is working great. This fence will save outfitter from having to hang food in trees. Also several fences can be hooked together to make a perimeter around your camp.
