| Comment | Some interesting history about the 90, as the "Inner Circle" - originally there were to be three circles, the Intermediate Circle only lasted a few years and the Outer Circle never materialised.
I can't remember where I originally read about this, but [someone on Flickr posted about it last month](https://flickr.com/photos/89656176@N08/51905014111).
FWIW I missed the 90 by about 30 seconds today, thankfully a tiny wee McGills 121 wasn't long behind. |
