Noticed this weird-looking section of hedgerow on the way up to my parents’ yesterday. We were behind schedule so didn’t have time to stop and investigate.
Fortunately, it wasn’t too far away so I was able to go back later and have a proper look.

Sadly I didn’t have the presence of mind to take my drone with me (NB: always take your drone with you), as I think this would have made a perfect, last-minute entry to the RTF Competition - Construction
