This afternoon, a 65yr old Swiss cyclotourist, not wearing a helmet, fell over his handle bars when he didn't manage to control his speed while going downhill at Nova Pec, Czech rep. He teared his face and broke his frontal lobe, was transported by helicopter to Ceske Budejovice traumatology ICU, where he is being taken care of. It was an organized bus/cyclotour.
