This thread has puzzled me for some time ....
I grew up around Chicago, even lived on the North Side for a while .... and never really noticed horizontal receptacles. The only places I remember them was where they were placed at floor level, in the baseboard. I was away from the area for most of the 80's though, and haven't been back since 92.
So I watched one of those 'flip this place' shows, that was set in Chicago. Sure enough, all the remodels had the receptacles horizontal. Curious.
