Thanks for reminding me of that documentary. I followed her story for a while, when the film was till in development - but forgot it. I don't have streaming video and have low internet bandwidth, so I'm going to order it on DVD (it's linked to Amazon for $25). I can also watch it at a friend's house on one of the streaming services.
For those not aware of it, see:

Sadly, I don't even go "home" to TN anymore, as it's a sea of blood-red bullshit. I've lost contact with all of my 1965 classmates because of that dilemma. It's sickening and un-American the way they've divided us. So, I feel your pain!
