My new neighbour, with whom we have cultivated good relations by lending
him tools etc. etc. has renewed his side of the ?joint? tarmac drive.
The boundary was marked by the remains of the lone gone fence. Which is
now covered by tarmac to a few of inches on my side, which is a great
improvement so I am not complaining, but I have apparently lost a few
inches of land. I had previously marked the boundary at both ends by
chisel marks in concrete, so a bit of string will tell me where it is.

Has any one any good ideas as to how I could re-mark the boundary?
I was thinking of whacking thin line with a bolster.

Nails 30cm apart?

Even if the heads rust away, you could find them with cable sensor
