Dear RC, All kidding aside, and with deep serious here. I've been in business since 1986, and every customer I've talked to wants to "get someone close". So, if you put nothing else in your ad, be doubledamn sure to put your store location. I mean, people will call and say "Oh, you're in...." and ask me what town I'm in. It's that important to people.
I tried an ad one time which said "Residential, automotive, industrial, commercial" and said what two counties I wanted to serve. It drew almost no business. People would look at the phone number, and try to figure out from that where I am.
