Also keep in mind that my geo-targeting is set to a list of select cities, so even though I'm using some broad match here, it's only being sent to a select audience. Broad match would be appropriate because I would have search terms such as:

counselors for couples near springfield, NY (i.e.)

I def. want to hit that query and as long as I'm marketing to that location, I see no problem with including these broad match keywords.
