Colinton Tunnel rainbow :-)
I've blipped the Colinton Tunnel before - but our daily exercise today (trying to keep up the Tuesday-jogging!) took us along that route; and I was delighted to see a rainbow has now been completed up-and-over the roof ...
... as before; you can read much more about the tunnel project here, and Chris Rutterford (the main artist) has a website here.
Thought this a *very appropriate* image for our current times :-)
