I found it interesting that Cynthia Burr, as Katherine Blake, is only credited with 2 episode appearances. I have seen every episode as I assist my wife in her ESL class, and they use Crossroads Cafe as the basis for their teaching. Also, at one time, and perhaps still do, Raleigh's PBS station replayed all of the episodes a number of times.
Cynthia, along with 5 other actors/actresses, are the key cast members of every episode. The same can be said about David Kirkwood, Jess Washington, who is only credited with 1 episode. It has been a while, so I may have forgotten, but to the best of my recollection, all 6 primary cast members are present in all 26 episodes.
At first, I watched the shows strictly to assist my wife's learning (She is Chinese) but as time went on I began to enjoy the episodes myself, and actually set a DVR Timer for the show on the PBS Channel. All 26 episodes I saved on my wife's computer.
