"For everyone's future reference, all wood poles are Minnesota Power's responsibility, so you can call them for wood poles' light problems. The City of Duluth's poles are metal, and you can call or email us to report problems. Lisa Potswald, Director of Public Administration, City of Duluth."

Taken from another website. But this information is seriously too hard to find. If you go to the Comfort System website (to whom we pay a street light fee) they do NOT post this information; at least in a logical and easily found place - say the streetlight page. And I seem to remember having to search for the information on the Minnesota Power website as well.
