I have just sen the "Road To Paris" special on the preparation of the USPS and let me tell you it is very good. OUt of the many documentaries I have seen on cycling insight this one is very good.
No indepth stuff as it is too private but very good overview on the directors chair.
I reccomend everyone see it. Especially if you have many questions or want to know more on the "lifestyle"
From being on that side myself I have to say it is very good and a good overview from the director.
