Employees of the heart institute served food to help save lives today. They worked at the Sonic on Frank street from 6 a.m. to 3 p.m. as car hops. All the tips they made will go to benefit the American heart association. The group says it's fundraisers like these that could eventually help find a cure for heart disease which kills more people than cancer each year. Workers at the heart institute will be holding fundraisers over the next few months leading up to the heart walk in the Fall.
