Buildings here may need remapping - they don't match my recollection. Lots of construction work still taking place.

A number of the names here could benefit from on-the-ground checking. "DOVEHEAD" etc. seems excessively shouty (and suspect); and both "Dry Stones Edage" and "Knotbury Edage" sound like typos. OS Locator doesn't have data here (although by itself that doesn't mean these names are wrong).

Is http://www.openstreetmap.org/way/342101478 really best described as a cycleway? My recollection was that there wasn't much in Twyford wood that could be described as that (bits of concrete, former runways). Also, presumably it joins at both ends?

http://www.openstreetmap.org/way/315372199/history needs a proper survey. Doesn't look like farmland based on the imagery.

Is this (a) really called "Byway" and (b) really an unclassified road? Needs a survey.

From looking at https://www.openstreetmap.org/way/446141461/history it's clear that a new mapper is trying to edit the access here. It'd be useful if anyone with local knowledge could get in contact with them and help them.

Is http://www.openstreetmap.org/way/371413708 here really called WRU EIH 09MU-23-8-22 ? It seems a very unlikely name.
