Surveying.

Ginny walk along the seafront on another dull day weatherwise.  Not raining but damp on the pavements and mucky - being low to the ground she kicked up a lot of grime underneath.  Proper rain would wash down the pavements and she'd just be wet but not mucky.  So it was a quick bath for her when we got home.  
When I saw these two guys I wondered what they were finding to photograph - I thought it was only Blippers who took pretty bland shots of the Estuary of necessity when there's little else to shoot!  As they were still there on the way back I thought I would ask - surveying the birds - I think they have telescopes not cameras.  Took their picture!
