The story of discovering the hidden past of Angel Island - the incarceratioon of Chinese immigrants - is told very well by Hana Baba.
Her approach is in synch with a ranger's story, hearing his footsteps in the "jail" area as he explains the evidence he found of Chinese people being held when they arrived at the "Ellis Island of the West".
Baba's writing is clear as she introduces new voices and perspectives, including a Chinese woman who suffered the detention and humiliation and someone reading the Chinese poems written on the cell walls.
This piece is network quality and deserves to be heard. May I suggest around July 4.
