Placidfemme - Go along the Nor-western motorway.. they love sitting there catching people heading into the city...
They also park along Gt Nrth Rd top of the hill by Kelston Community Hall.
Swanson Rd.

They are all over west Auckland.
And they also use station wagons as well.

Look for any older vans parked on the side of the motorway or open roads...
look real careful... cos they usually are the speed camera vehicles.
Dont you go thinking that they are vehicles that have broken down.
