Puzzle II

Isn't that near The Borders somewhere? I'm sure I've been there.

I don't know the name of the place... I seem to remember Judith Chalmers demonstrating the odd gravity effect years ago.

The other places are just slightly further north than "one mile north of south".

The distance around the world is about 26,000 miles at the equator, reducing as you move to the north or south poles, and zero at the poles. There must be a point near the south pole where the distance around the world is one mile exactly. Start one mile north of here. There must also be a place where the distance around the world is half a mile. Start one mile north of here. And so on.

Electric Brae is near Ayr. It's a place I used to frequent when I was courting various burrds.
There's no magic or spooky stuff happening, just an optical illusion caused by the landscape, the hill appears to be going upwards when in fact it's going down.
I've lost count of the number of choobs I've seen testing the effect by letting off their handbrake and freewheeling.

I never have, of course.
