DH is an electrician. I read this out to him and he said that on a misty night, you can go under the pylons and hold a fluro tube up and it will light up. The guys he went to trade school had done this, and so had the teacher. There's enough magnetic field around them to effect a person. Neither of us would live near them. There's nothing on power companies websites that say anything about them and no official authority will actually speak about it if pressed. That's enough to make me worry. When we built where we are, there are some in the area, and we were careful which side of the major road we built on.
