Podcasts are the best thing about the iPod phenomena, and there is a new one out there all about Twilight. The podcast is called Drive Like Cullens, and it was created by "a group of friends/siblings who are fans of Twilight." You can also find them on Facebook, where you can and should [as a Twilight fan] become a fan of their page.
I'm only Episode 2, but so far I like it! They have good rapport with one another and their discussions are witty and make me laugh. Of course, I am may be a little biased since I used to work at the school they all went to, but hey, what can I say? I am always happy to support people with whom I have some sort of connection! Plus I have to confess that I feel a little better about my Twilight obsession since Alyssa saw Twilight in the theaters four more times than I did.
