I was taking a stroll through Kensington Gardens in London when I saw this on the path. Apparently there are 90 of these plaques embedded in the ground leading you around a 7 mile walk through some of the main parks in London.
You do find nature reserves squeezed into some interesting spots. Rye Meads Nature Reserve is near Hoddesdon on the Essex/Hertfordshire border squeezed between two large towns – Hoddesdon and Harlow. Power lines march relentlessly across the vista across to the large chimneys in the distance.
