I was actually wondering that from the very beginning. Normally I'm one of the last guys to shout "Photoshopped!", but this made me wonder. I mean, don't the leafs look like maple leafs? Because I'm pretty certain, that the trees are not maple... But then again, maple trees can grow in so many different shapes, depending on the place they are growing in/at/on/...whatever.
It's still a nice picture though.
