I was pleasantly surprised how relaxed it all was.
The only person who seemed to be wearing a hi viz was some bloke wandering round taking photo's of the shack and other things. the whole place seems to be a bit of a scrap yard to be honest in a nice interesting way.
I think if you try and be daft and cut across brum zone your maybe going to get a hard time of it but if you just track a bit further north and then come in North of the 101 Hon radial I can't see any gotchas.
