Good point about the water bottle.

During the DtF last year, they showed one of the helper guys filling his shirt with water bottles from a car in the back and then going up to give everyone some. So I'm imaginging some poor domestique riding through most of the race with water bottles kept clean in his shirt, and at the last minute handing one over.

But I'm guessing really, he got it after he finished, had some water, and stuck it in the holder.
