OK guys, I'm a little thick here but bear with me... I'm still trying to mentally locate where this bivouac camping is.
You head toward the grandstands, you've got Maison Blanche on the right, Bleu on the left, and a crowd of drunken loonies between the two. To enter Bleu, you pass the campsite and enter on the left. You then make another left to enter the campsite proper. To the right is a large parking lot - is this the bivouac area? If not, where is the bivouac area with respect to the Bleu lay-by area?
Thanks again!
