I had one of my best runs in my Lefroy mini, on Hepburn Avenue [northern suburbs of Perth] a few years ago.
The stretch of road had only just been finished, and wasn't yet [officially] open to traffic.
I was clocked at a bit over 80 klicks by the security blokes in their ute - and Mr Plod was waiting down the road [not for me - for hoons]
Only problem I had was getting the Senior Connie out of the landyacht.
The security blokes and the younger constable reckoned he was having too much fun.
===========================
One of our W.A. land yachters transports his L.Y. by hanging it on the back of his ute via a bracket on the towbar.
He used to remove his number plate from the ute and hang it on the L.Y. so it wasn't obscured [an offence here]
When we found out you can have auxiliary plates issued by the transport dept., Chook got one and bolted it on the landyacht permanently.
It saved his neck when a council ranger was about to book him for unlicensed vehicle on a public beach.
Ranger didn't twig that the L.Y. plate was the same number as the ute.
Chook got to keep happily sailing on the beach with his kinda-sorta licensed landyacht
