This poster summed it up perfectly. Only reason I can see for going there is if you are going to be with a loud group to party and don't want to disturb anyone. Dear God don't go there!
I drive by it every year heading other places, you could throw a stick at it from your car and Achray road in the summer is for all intents and purposes a busy highway, you'll be covered in dust in an hour....
If you want to drive to a campsite along that road, head in to Sec/Mallard lake, it's off the main road and will get far less traffic, if you have a canoe, paddle out from a lake like Sec or Mcmanus and find a quite spot on the other side!
