Two question to either one of the whole group.
You have told us you kept uploading waypoints at your night camp. Assuming you use some form of laptop, where'd you get the power? Can't imagine there are any sockets in the middle of the Mongolian steppe.
And is there a particular reason you all go from West of East? Is it inadvisable to go the other way around, or did it just turn out this way?
Keep the updates coming!
