Here are the links to some of the key web pages about the 2011 Tour Divide:
Tour Divide web page - the main source of info. Lots of content here. I am in the start list for 2011 Grand depart. http://tourdivide.org/
Interactive map showing the route and elevation. I used this to make my plans. I am traveling North to South.

MTB Cast.com - the page with the audio call in reports: http://mtbcast.com/site2/
Facebook group: "Richard Ridlehuber can finish the Tour Divide by July 4th" Search it in Facebook and ask to be a member.
Link to a Beta version of a web page that displays: the route, weather, snowpack information, and rider location. It is not updated with the 2011 participants yet and doesn't display correctly on some computers. http://bluedot.mobi/td
NOAA Snowpack webpage: NOAA Snowpack data
There are record amounts of snow on the course this year. It is a huge factor. Those who decide to bypass it, forfeit there claims of doing the "official route". Those who choose to go through it, will be slower. I plan to go through it - I've got one chance to do this event and I don't want to compromise my results with a detour.
