I just returned from Washington DC 2 weeks ago and it was a great trip... In DC, there is a law passed from long ago that buildings cannot be taller than a specified height.
Coupled with the fact that there are no heavy industries around the area, the sky is perfect for photography - blue, vast and with the occasional cloud trails from the planes taking off from Reagan National Airport.
The opportunity for shooting a good stock photo is abundant and I have submitted a few of the better ones I got here... How I wish my own country has such sceneries too :)
