How do I convince people to support NASCAR radio broacast in the Twin Cites (Minneapolis/St. Paul)?

I have tried for months since we lost a radio station here. I launched a one-man campaign to get a radio home for live NASCAR racing in the Twin Cities. It has been partially successful in that I found a station that could do it. I soon found out that there was not much public support locally for such programming, so I wrote to the major newspapers in my area, but neither published my letters. I tried writing to a local radio personality asking him to tell listeners to support my cause; I do not know if this has worked yet. I really want to do this because I do not have cable or satellite television service at home despite the switch from og to digital television in the near future.
