What goes on behind

Backflip no.2
Decided to take random 'behind me' shots this week, to see what goes on behind when you are walking away. Decided this one was interesting with the tree 'reaching' out from another angle.
It just gets difficult when your finger is chilled and you've no idea where the button is! It is an interesting way of taking photos as when you see someone or something approaching you, you weigh up how good a shot they or it would be when they have gone past but you do not look behind! Anyway.
