Three Knoxville Northstar Elementary students are making the world a better place by providing free lawn care to elders, those who are disabled, single mothers and veterans. Brendon, Jayden, and Bryson Wood are participating in the program Raising Men and Women Lawn Care Service. The young men say they very much enjoy helping everyone. With enough service, they will win a lawn mower, a leaf blower, and a weedeater that will help them set up a lawn care service should they want to.
