Urban Trees - Trees In The City

Brief

In this contest, I want to see your photos of trees within an urban environment. Use of architecture or buildings is favourable but not a must, and I am particularly fond of an image that shows nature's frailty or isolation in a concrete jungle. Try to make use of lines, shapes, symmetry, reflections and vanishing points. Images could be in colour or black and white and captured in the day or at night.
