Judy, We will have no idea of where it will air . We will also have to go to our local stations to find out.
On our website on the right side there is a link that takes you to PBS listings. This series is not PBS produced so it will not have a national air date. Stations can choose to air it or not. Hope this helps and thanks for your interest.

Guess we will all have to keep checking our PBS stations from time to time.
