Ive laid out powerlines across most of the ACT and Queanbeyan, so feel
free to do the line from the wind farm to the Queanbeyan sub-station.

I wonder if there are any plans to do so?  It would be great to have
nearmap imagery along the NSW coast, the same as is being done along the
Victorian coast.

compass, pen/paper and a little bit of high-school maths.
