If you want to follow the tour, but don't have OLN, follow the live blogs on http://www.letour.fr/ or http://www.velonews.com/. Not the same as seeing it on screen, but better than nothing! Racing begins at 8:30am and goes until approximately 11:30. OLN usually does an evening show of race highlights, but this year it is notably absent.
Finally, check out this photo ... what's the caption? (Left: Alberto Contador. Right: Lance Armstrong. They get along like oil and vinegar.)
