I wonder if it's worth Pugfan buying a Bleu Nord camping pass (think Paddy has some), if it's allocated pitches then they could drive in and out ok.
It's on what I would regard as the right side of the circuit and will access to toilets if the guys are planning to sleep in and live out of the van?
No issues about a barrier and if Paddy is offloading his passes on here then they would be in and around CA'ers.
That sounds like a mighty fine idea to me. Hopefully Paddy is watching this topic
