I find the occasional footage from Pripyat fascinating and also that Japanese Island when film is occasionally released, the way nature reclaims land in such short periods of time is amazing, just be glad japanese knotweed is not endemic to the UK that stuff pushes through solid concrete. But I was truly fascinated to see how quickly trees started to grow almost everywhere.

Anyone remember what that creeping carpet type wed is with the small yellow flowers, it covers up the cycle tracks around here every year with a good inch of foliage?
