The sentiment was expressed by Medco President Kenneth Klepper in The Courier-Journal of Louisville.
Kentucky offered $30 million in incentives to lure the project, which will employ 1,300, to Louisville. Indiana offered $18.6 million.
Klepper also has said Indianapolis was picked for its central location and presence of pharmacy programs at Butler and Purdue universities. Locating near Indianapolis International Airport, where FedEx has a hub, was another reason for the decision, he explained.
Medco, headquartered in Franklin Lakes, N.J., plans to announce a specific site in Boone, Hendricks or Johnson county in the next 30 days and complete the facility in 2009.
