Rascal Flatts will help volunteers build a playground in Birmingham, Ala., on Wednesday (Oct. 15). The band won the Academy of Country Music/The Home Depot Humanitarian Award earlier this year. Recipients are honored with a KaBOOM! playground built in the city of their choice. The construction project will take place at Princeton Alternative Elementary School. Volunteers include representatives of the ACM, The Home Depot and KaBOOM!, as well as members of the community.
