Campaign for Real Aires UK - CAMpRA

Do we have a list of aires?
I didn't spot one...

Obviously it would take some work to maintain, as new places keep being added, but I would think it is worth doing.
A map would be even better, but substantially harder.

I'd never heard it (apart from in the river) before I happened upon this group.

Sorry if this is a silly question, but where does the word "Aire" come from?
I presume it originates from the "Aires de Service" in France, but the direct translation is "Area" and that doesn't make sense on its own.
