Discovered that as well - at first thought I was too distracted by the grass under the trams!
Second note: believe (as mentioned in another thread) the navettes are now virtually useless. With the possible exception of between 3am and 6am on Sunday. Waits at Arnage on Saturday evening were up to an hour, at Mulsanne at 1am Sunday we gave up and walked back to Arnage after waiting an hour during which time 5 busses arrived, but only 3 or 4 folk were exiting and so only 3 or 4 allowed on. Which made no impact on a queue (?scrum) of circa 200. 1 of whom was given a lesson in queuing though
Another update I will do for Arnage campsite: pitches were pegged out and space allocation was pretty orderly and well policed. Even more unannounced, it was ready for service Tuesday afternoon when we pitched, which was a bit of a blow to the regulars arriving first thing Wednesday morning
