Highway to Hell Zine
From Super-wiki
In June 2006, Supernatural fans agt_spooky and charityflint decided to put together the first Supernatural Wincest zine. They conducted a poll to decide a title, settling on "Highway to Hell" (the name of an AC/DC song used in 1.01). Submissions were set to close in September, 2006.
The zine was finally published in 2007, even thought it initially had received only a handful of submissions. It has a color cover and contains 10 stories and 147 pages.
All the planning posts can be found in agt_spooky's LJ, here and more information about the zine can be found here.
A second issue may have been published in 2009, although this has not been confirmed.
