Looking Up

I do so love trees.
Looking up at them in all their majesty is delightful. It also has 3 basic perils. 
1) There is a chance of tripping up when you don't look where you're going. 
2) There is a chance you'll miss seeing the 50p (insert any amount of single coinage here) that's lying on the pavement. 
3) There is a chance a dollop of something white may be delivered into your eye.
Still, trees are so beautiful and there to be looked at.
