The world needs more people like Rodney Smith Jr. He's on a mission to make a difference, one lawn at a time. At least that's how it started.

Rodney is traveling the country and mowing lawns for single moms, veterans and elderly folks who have a tough time taking care of it on their own. And now he's encouraging kids to do the same.

Now, Rodney has inspired people all over the country to do the same, so it's hard to tell how many lawns are being taken care at a time.
