Took this picture at my bosses' house. The office is on the second floor and I opened the window and sat on the sill, hanging half way out over the front porch.
I'm such a dare-devil :p
What you're looking at is the top of a Bradford Pear tree, which right now is in bloom with pretty white flowers. Unfortunately these trees also have a rather strong scent to them which, I'm not sure I'd describe as pleasant. Good thing scent doesn't travel through the internet!
