You have to have one or two little luxuries at Le Mans, but no heated hair rollers please.
Can you still get electrics from the street lights? We were doing this about ten years ago. There was a box at the bottom of the lamppost with 4 big brass bolts in it that you could hook into, but then a man came along and moved it all about 20 foot up the lamp post.
Its still one of my best memories, seeing Gary balance on a pile of tyres, half pissed, hooking into live mains, only to be told he'd got live and neutral reversed.
After years of training (as an accountant) I seem to have become team electrician, but I do know enough to unplug the lot, when neutral and live fail, but earth is at 100 volts.
