If anyone is up for a long ride over night, this looks interesting. I would love to do this ride, but i have realised it clashes with a family function, so i just won't be able to go unfortunately. It looks great though, and would encourage people to go if they are up for it. You don't even have to do the entire ride, you can bail out at Gosford or one of the many train stations along the way.
Go for it... enjoy
