for the best TDF coverage, go to bicycling.com/tourdefrance Go to Minute by Minute and read backwards for each stage; it's the next best thing to watching it on OLN.
Also, I usually update every couple of days on edited my site and I'll update more often since the mountain stages start in earnest tomorrow. This is for if you don't feel like reading the whole minute by minute thing. I've learned more from the bicycling.com site than almost anything else. WEll, that and the 5 magazines with lance on teh cover that I've read this year.
