Thanks, Harry!

I suggested mapping them in the talk-gb mailing list about a year ago and I think there was support that there are some use cases. In particular I want to be able to do comparisons of different councils' attempts to meet demand and to provide accessible safe bike storage for people who don't have homes big enough to store a bike (or multiple bikes in the case of families) inside.
Please do add any others you know of!
