This footpath needs a proper survey. Presumably it joins Bowling Alley Lane, but exactly how (stiles, gates, etc.) needs to be discovered.

The footpath that runs south of here needs a proper survey. It seems to get through hedges without using stiles or gates, and runs right through at least one farmhouse. It probably also joins the road here rather than the landuse.

I'm guessing that the two bridleways here are actually one and the same, and the actual place where it joins the road is around where this marker is. Needs survey.

Need to survey to see exactly how this footpath joins the road here (stiles, gates, etc.)

As drawn, this footpath is clearly rubbish. I suspect that from the west it actually joins the stub to the northeast of here, rather than connecting to the wrong side of the bridge.

Need to have a look to see how the (mostly artificial?) north-south channel interacts with the natural east-west streams. Does it act as some sort of load balancer, or a feeder for something else?

Presumably this footpath joins the main road, but does it go right past the pub or into the car park first?

Presumably the footpath from the south here joins the path to the north of it? You can't see from the imagery because of tree cover, but it seems pretty likely.

Node osm.org/node/3133738122 needs a tag that would enable people who are looking for services like this to actually find it.

suggests "craft=plumber"; would that make sense?

There are two "Harmston Heath" localities here. I assume that this is just copy-and-pasting from OS OpenData, and in reality there is either zero or 1 places with that name?
