I'm not sure this is the correct place to ask this question and/or make this suggestion, and I apologize if it's not! I've been watching the PBS - Carrier - and I am enjoying the series tremendously. I've a few questions and comments about the series and wonder if it's possible to start a discussion on the series in the hopes that someone can answer the questions and review the comments. If this is not the right place for this type of dialog, is there an area on PBS for discussing the series? I've searched and searched and have not found anything. Thank you.
