The problem with back blipping is that I can't remember what happened.
Most days have midday yomps around the quayside and most days I can spot a cormorant.
I took this from the balcony at work with wee zoomy before the Naval Reserves had the millennium bridge raised at 8am.

Ah! Now I remember! I didn't have a lunchtime yomp around. I met Beloved for lunch as I'd forgotten my phone.
Didn't forget my camera though!
