The thin blue line

A trip over to Snettisham seeing as how we are getting some decent weather at the moment.
 The blue rope in the main is put up by the RSBP and is there to designate the no go areas where ground nesting birds can safely lay their eggs. We just have to hope the birds understand this and lay their eggs on the right side of the rope. 
Extras = (1) Slightly eider blue line. 
And, keeping to the blue theme, 
(2) Viper's-Bugloss.
