Hey,well, my money is on deciphering a phone number with extension out of the letters in the clues we've got. in order. I think we'll get more letters tonight.
I've been looking around for cool things to do after Push is over (sad it's been cut short, although I don't kow what I'd do with even more hints! 
I found this place while I was surfing around for puzzles, mysteries, etc. Has anyone else heard of it? I just sign-ed up but want to know more. www.puzzlerally.com

The more I think about http://www.puzzlerally.com the more I think it'll be a cool place to be to recapture the excitement of push.I don't have hope on the "blood orange" idea. In the Oct 17 episode, there are a few morse code examples in the opening credits, the 3rd of which is clearly (simply) "orange". I did notice some red colors in that episode also, but my money is on orange. Now only if I can figure out what to do with the 13 clues.
I think 877 is toll free in the US. I used to think that we had to derive the number (and an extension) from the 13 clues. I no longer think that's the case.

Good luck to everybody tonight! may the force be with you and hopefully reveal something obvious to you that isn't yet obvious to me!
