How much does a billboard along one of the highways go for in Columbus? I'm willing to contribute $20 if someone will get this organized and then we can all pitch in and get our message across. Simply, "Fire Greg Andrulis" would do the trick. http://www.billboardsusainc.com/fhome.html The above website has 10'x30' billboards for $400. I think that's a reachable number, as long as there is a comparable number for a sign in Columbus.
Interesting idea, and not without precedent. The DC Fans hired a plane that trailed a "Fire Rongen" banner several years ago over the stadium during a game.
