A lot of these people drive to/from their jobs, and some even listen to music while they work...
so why not a radio ad?
We're way ahead of you, johnj.

Ad placement isn't my forte'. Anyone have any sway in radio advertising? It would be interesting to find out what sort of costs we are looking at in the top 25 DMAs.
Another thought would be to cut a commercial in Spanish. I live in Dallas and there is a huge Mexican immigrant population here and other cities in border states like Houston, San Diego, Los Angeles and Phoenix. The spanish radio stations reach a very large market. Many of this audience is looking for better and more safe ways to send money back to relatives in Mexico.
