Can any dopers point me towards a truly detailed map of the area codes in Wisconsin?
I’m not looking for broad general maps. What I need are maps that’ll take the area code borders down to street-by-street levels if I can find them that detailed. I’m not really interested in the 715 area code, but I am for the rest of them.
My google-fu must be weak, I’ve not found anything fitting my specifications thus far. Hence I turn to the Teeming Millions.
Thanks in advance!
