Is this really clay lane?
At entrance of Berrystead it says “private road” and my guess is this limb is also Berrystead, with clay lane the ancient byway running parallel NW to join Cow Lane

School is due to move soon to Mapledurham Playing Fields (see note up there)

This area needs checking generally against aerial once that's available. In particular there is an embankment running parallel with the road (but not part of the road's own embankment) with (?)noise-cancelling fencing on top.

Creake Abbey could do with fuller heritage tags.

It also appears to have two nodes associated with it, with different names and different tags on each.

Is this the name on the ground, or a description?
