I think we should actually start discussing the episode and not the finding now. Just so you know, my code is CS for "Classic Season"!
I was really excited to see this, mainly because it is our beloved Brigadier's first story. So far, I am not disappointed. It is brilliant! If it was a UNIT story, I think it would be my favorite. I have just finished pt4, and that was such a surprise to see the Yeti walking the streets in a full out battle with the troops. I can't wait to watch the remainder.
