Tunnel Vision

I grabbed this shot as I was rocking around the streets of Edinburgh in the wee small hours.
Walking along a street lined with tall buildings and suddenly there's a narrow alley with the Castle, all lit up, at the end of it.

At the time it just seemed like an unusual view of the Castle.
Now that the effects of the night have finally subsided, it actually seems like a metaphor for the evening.

A vague blur of randomness punctuated by the occasion moment of clarity!
