Rev Richard Coles, presenter on BBC Radio Four’s Saturday Live, once described the plastic bags suspended along the roadside on his drive home as looking like “Unfortunate wraiths snagged in trees”. Sadly a common feature along the River Thames. More ‘wildling’ trees along the Thames footpath near Mortlake. A ‘wildling’ Plane tree growing out of the cobbled embankment along the River Thames between Chiswick and Kew.
