Review: Priceless Campsites & Rest Areas in North WA

We looking to travel around NT and WA for 5 weeks and have spent an enormous time trollng the net to find where to camp etc before discovering this book.
Put simply it is brilliant - complete descriptions, detailed directions, local attractions and sights, GPS co-ordinates and even tells you if you can get there by 2wd or 4wd and if you can have camp fires.
