On Monday, millions around the country honored the memory of Dr. Martin Luther King. In Philadelphia, Liberty Coca-Cola and Pepsi joined to celebrate by taking part in a service project at a local school.

The two beverage companies, along with Philadelphia Councilwoman Maria Quinones Sanchez’s office and the Philadelphia Beverage Association, refurbished a local middle school in a distressed part of the city. Volunteers spent the day painting the cafeteria and other common areas, and assembling recreation equipment for the school’s after-school program.

There is no better illustration of our industry—competitors coming together to make our communities a better place.
