I know this thread is a bit of fun but I'll be the "kill joy" here. Just be careful out there guys.
We don't want any of you to end up like Fabio Casartelli:
"On July 18th, 1995, during stage 15 of the Tour de France in the Pyrenees from Saint Girons to Crête du Lys, Fabio Casartelli crashed and was tragically killed. On the descent of Col de Portet d'Aspet (with parts of 15%) Fabio Casartelli hit a low concrete wall with his head wearing no helmet. On his way to the hospital in the helicopter he died after 3 heart attacks."
