These aren't skyline pictures, but I thought that they fit the thread anyway, and they would be particularly enjoyable in here.
What you see in the pictures here is the ability to look clear across an entire state. I took these pictures yesterday from Edgar Price Road in Maryland, just barely. The intersection that you see in the foreground is the intersection of Edgar Price Road with Maryland Line Road, just within Delaware. Edgar Price Road continues straight, but is called Levels Road in Delaware (because of how flat the farmland was, being around the crest of the Delmarva Peninsula).
Way off in the distance is the Salem Nuclear Power Plant near Salem, New Jersey. Not only can you see the cloud from the plant, but you can see the cooling tower itself: a physical object in New Jersey, visible from Maryland while standing on the ground.
If you're wondering why there's no little "Welcome to Delaware" sign in the picture, it's because Edgar Price Road is a dead end that just provides access to a few farms. US 301 cuts the farms off from the rest of Maryland. But the change in pavement indicates the state line.
Here's the spot where I took the pictures from.
