You can find the Sheppard skiiing AU here (http://community.livejournal.com/sga_flashfic/692866.html). It turns into heavy McKay/Sheppard at the end, but the skiing descriptions are just awesome :) And there were a load of snow ones for the freezing challenge at sga_flashfic. Although sadly, very little skiing.
