The beach off Aberlady Nature reserve is never crowded partly because it involves a 2 km walk and is not suitable for swimming. I counted nine people on the beach although there were many more walkers and birdwatchers on the reserve.  The wooden pole is a remnant of the anti-glider posts which were put up on east coast beaches in fear of invasion during WW2.  Officially classed as air-immobilisation posts, the posts would originally have been about ten feet high when installed, supported by four 3-foot spars attached at their base. The posts have been cut down to a height of three feet, or less where they have rotted away over the years. The posts were arranged in irregular rows, at intervals of about 20 feet, to prevent gliders or aircraft from landing on the beach.
The extra is looking back over the beach from the high rocks in the background.
