Thanks so much, Rod, for confirming my guess. I first learned about CSAs from a workshop by Traugher in the early 2000s; must have been  BDA conference, though can't quite remember where. But, I think about what I learned there all the time.

If you have photos or would like to share your story, please let the BDA know.
