I'm sorry, but I think it is misleading to suggest you have a listing of all the PBS stations carrying KD TV on your website. What you DO have is a space where we can fill in a zip code to discover if our local PBS carries the show. I live in the KC area and it is not carried here. I have no clue what other area cities might carry the show. I suppose I could look up the zip codes and plug them in, but that is hardly what one would call a listing of the cities.
Also, I was glad to read the comments before ordering the DVDs. I think the show needs more refining and paring down to be more specific rather than just being able to say they are on the air.
