Hi,
It did not seem like a question, so I did not reply, just took your information on board.
As for more to do, I don't know to be honest, don't keep a 'file' of what I do either mentally or physically - I was just going to be more aware as I was looking over the area. I was doing Penrith to Scotch Corner both sides of the A66 for several Km as it's a route I do often and decided to enhance it (or so I thought).

My point still stands that any mistake or edit on OSM can be re-edited and fixed. Except this one of changeset descriptions.
I, like everyone could do more of this or that. But my balance of incentive and time generally drives me to what I do. no more no less. I generally tidy up rural areas cos it's my thing, and it gets little attention by others. To do more of what you ask would make it not cost effective for my "mind" and I would cease working on OSM. Each change usually affects streams, quarries, farms, isolated dwellings woods etc. and I'm never going to document each one as it's a waste of my time..

I can't make sure of anything. Mistakes happen - to you even I bet! The browser editor pre-fills in with the last choice, and if I forget to change it, then I forget, simple. The program does not allow a retrospective edit of the note - that's perhaps where effort should be directed?. So that's that I'm afraid.
