Enclosed you will find a couple photographs of a telephone line and railroad signal line, both with several telephoto views of insulators found on the lines (not on one pole, but several poles). Thirty years or so from now these lines will be long gone, a thing in the past. 

I not only collect insulators, but I also take telephoto pictures of old insulators in service -- from telegraph lines to transmission lines. Whenever I go on a trip, I keep my eyes open for any old lines that are worthwhile to take telephoto pictures of. 

I would be interested to know if there is anyone other than myself taking telephoto pictures of old insulators on lines. Paul Mohrs says that Scott Given takes photographs of old lines in the Ohio Valley area.
