Elaine Cha steps out of the shadows into the St. Louis Public Radio spotlight

A latecomer to public broadcasting, Elaine Cha preferred to work behind the scenes.

Elaine explains why she brought out her on-air voice. She'll also look at how STL Public Radio has covered the tornado that blasted St. Louis in May - and the total solar eclipse that captivated the city last year.
