The 4th Annual Sakrete Sack Program is back! Sakrete®, North America's original dry cement mix brand, is an official sponsor of the Carolina Panthers for the 2009/2010 football season. As part of the company’s commitment to help give back to the community, Sakrete will donate $100.00 dollars for every quarterback sack during the regular football season to the Charlotte Business Volunteer Council (BVC) playground build. Pawtuckett Elementary has been chosen for next year's playground build.
