Specifications include, but are not limited to: MDC requires advertising with the River City Rascals (legal name PS and J Professional Baseball Club LLC) to support MDC’s Trees Work campaign in a targeted region and to promote the value and benefits of Missouri’s tress and forests. The River City Rascals plays on the Carsheild Field owned by the City of O’Fallon and the city has been actively engaged in addressing tree health, maintenance, and care at the ballpark, particularly with the replacement of dying ash trees at the ballpark. Therefore, advertising MDC’s Trees Work campaign with the River City Rascals qualifies as a single feasible source since the ballpark is the only site in Missouri that is actively addressing the messaging needed by MDC and the value and benefits of the tress and the need to care for them.
