The company that made this sign is located in Burgundy, quite a hike from here.
The fences are not powered up except for those couple of months in the spring. Car batteries are the usual power source. This fence blocks one of the paths that Callie and I like to take on afternoon walks. Right now, and during the rest of the year when the power is off, the grower lowers the fence at the path's access point so that people can cross over safely. When the power's on, we find other places to stroll. Callie encountered the electrified fences once or twice when she was a pup and has learned to keep clear of them.
