Navigating her senior years in a way that defies superlatives, Ms. Opal Lee, Fort Worth's most famous citizen who's lovingly known as the "Grandmother of Juneteenth," is now a centenarian.

And she is not only thankful to have reached this milestone but also adamant that she still has something to show the younger generation.

"It's good to be here! At 100 years old? Good gracious a life!" she said in a sit-down interview with CBS Texas anchor and reporter Robbie Owens.
