The annual Toby Keith & Friends Golf Classic is set for May 21-22 in Norman, Okla., with proceeds slated to aid severely ill children and their families at the Oklahoma University Medical Center. Keith has collected nearly $3 million for charity with the event. Its most visible aid came with the renovation of a pediatric cancer center that began in 2008. Earnings this year will back the establishment of the OK Kids Korral, a 16-room guest lodge on the OUMC grounds that will house patients and their families. The 30,000-square-foot structure is scheduled to open in 2012.
