While watching the news I heard about two trees, a willow and a dawn redwood, at 1514 and 1516 Brooks Avenue in Raleigh. The trees grew near the electric wires, so the utility claimed the right to remove them. The willow’s owner resisted, and the utility failed to make their case for removal...

No worries, apparently. Past owner saw them in 1976 when moving in. No signs of maintenance in the interim. 2014: the first cable looks quite new, the second had raveled one turn of the splice, which we 'remedied' by vinyl tape and circular clamps. Response growth is quite striking. One leader...
