i was curious about how riders relieved themselves. i heard about it before but could not remember. anyway,
here's the info... 
the other thing i was wondering about was litter. riders dump bottles/food containers all over the place, sometimes when their team car is right next to them. i guess somebody picks it all up, though.
finally, i'm not sure about the 2 x 2-pronged attack by the OLN call booth. it could be better if 3 of them were doing it at once...the tag team setup is a little strange. and nothing against bob roll, but his hard line against french inflection is kind of annoying. it would be funny to hear him call a soccer match between brazil and italy.
