i went to Alp Dhuez this year and was shocked at the behaviour of some "fans" ,there were some French on hairpin 10 of Alp Dhuez who booed and jeered every team sky vehicle that passed, they then threw a full bucket of water through the open window of a passing team Sky Jaguar.things got worse once the riders approached,throwing a handfulls of syringes in the air next to froome when he passed.on the second climb of the alp,they changed into lab coats in the the back of their van obvoiusly to cause more disruption,this was spotted by a few who held the doors shut (locking them in) until the main peleton had passed !!! once free they then decided to kick and punch anyone they could,running across the road and knocking a Europcar rider down.the fighting continued for a while and the local gendarmes didnt seen able to cope.even when the police arrived one broke free and punched another fan in the face.i had my 12 yr old son with me who found the whole episode quite disturbing and spoiled an otherwisw fantastic day.
