I hear/read that the enviro nazi types are dick-tating that the utilities can not trim the green crap near the lines, that in fact it's not the LINES or towers at all but the growth around it, which seems more logical than blaming the apparatus......so a line breaks in high wind, shit happens, ~100kv or so is a tad much to examine/maintain when live, so they need cut the power just to look at it, alternative is a pair of binocs......
