Lots of last minute events happen in their industry. You never know. This will not add cars but it really helps the morale of your group and it will make it easier to get volunteers for other fundraising events. It also does wonders for next year's annual car wash fundraiser. He loves to put a good spin on a story to help a worthy organization.
Car wash fundraiser events make good news the day of the car wash.
Car washes with big lines are big news. Pre-wash stories work if the reason for raising the money is newsworthy. That, of course, varies from station to station, region to region and story to story. I can't tell you what's newsworthy and what isn't. I have had lousy stories on t.v. and great stories with no call back.
