( Spoilers for Doctor Who Season 5 Finale ) I realize that this post is not very organized but it's four in the morning and I just finished watching the last Doctor Who episode. I haven't really had time to process it beyond "Wow, awesome."
So, I know I said I would tell you all about the convention but, I don't think I'd do it justice. And many others have captured it well. bellajayd referred me to Supernatural Wiki where they have all sorts of con info.
