At one point there is a corridor in southern ontario that had a hydro transmisison network. Over time, they got rid of the overhead cables, and they must have either burried them or did not need them anymore above ground. But there is one funny thing,. They removed the hydro towers and structures, but they left one free standing hydro tower all alone and never removed it. why you might ask? well thats what many others were wondering. It turns out one of the cell carriers decided to mount a cellsite up on there, they are probaly in a long term lease with the land owners as well, so when they took the towers down, they left the one lonely hydro tower alone, with no electrical lines on it, but you can sorta see the panels on it to identify it as a cell site. it would probaly cost more to re-erect a structure, re-tune it, point the panels at the proper angles, the azimuth, etc.. so they just kept it as is. lol.
