Is way/30916039 really called "The Big Track / Nottingham Canal Towpath"? Is "The Big Track" perhaps a route relation that this is part of and "Nottingham Canal Towpath" perhaps merely a description, in which case no name at all would be correct?

A cycleway=track extends on the south side west from here, but for how far?

This area looks like it would benefit from a survey to see how way/166056081 interacts with the track here. The imagery suggests that they share share a common part.

From the road and recent works it looks like the Derwent Aqueduct runs north-south here. What's the evidence for the easterly location ay node/2138163575

Footpath way/355307600 needs a survey; it's rather crudely drawn and there's no idea currently how it crosses the stream here, for example.

I'm guessing that what there actually is here apart from separate road, cycleway and footpath in the middle of a field is a road with a segregated cycleway on the southern side (perhaps cycleway=track; segregated=yes)?

way/355320341 needs a proper survey to see if it actually exists, and if so what the access rights along it are.

way/355310185 needs a survey to see if it actually exists, and isn't just a bunch of Strava users taking an illegal shortcut across a field. If it does exist, what are the access rights?

Lots of untagged stuff has been traced here, often with a "name" that helps identify it. In the case of the Vampire, there was a mailing list thread a bit back about tagging gate guardians that might help with what to tag it as.

node/30000436/history here needs checking, I think. On various OOC maps there's a "Brown Low" tumulus to the southeast and a peak of a different name to the north - needs a proper survey.
