Hiya Makara! :grouphug:to our old gang.
FYI no roundabouts on this Road but I kept a look out for some koppers logs which I didn't see
I did a google drive up Long Point Drive to approx where it looks like the search is taking place. That section of road is very straight with very good visibility of any oncoming cars, perfect to stop quickly without being seen. The speed limit is 80k (sign) but I'm thinking it would be easy to do over 100k along this straight. The scrub is really thick and there is a couple of water filled culverts along the way.
This first property (RHS) appears only to have a colour-bond shed with the property cleared, many people live in these 'American style' barns.
This Google maps say 2010 so there could be more houses around now.
