I didn't even know fandoms of such scope existed before I got into Supernatural when the first season aired in Australia. I still remember slamming to a halt in my loungeroom when I saw the ad for it, with the Impala cutting through the ghost on that lonely dark road, and thinking...wow, I HAVE to watch this!!!
Then came searching on the web for screencaps or promo pics I could download and use as screensavers, then I discovered fan sites, then I discovered fanfiction...and wrote my first fanfic around October 2006.
I still love writing, even though the words are slow to flow these days. And I still adore Supernatural - I still haven't lost that "wow" factor the pilot episode gave me.
