Living in NY, I have to exclude NYC out of pure bias, but I have to say Miami and Washington DC have amazing skylines.

Haven't traveled enough to come up with more than that. :-(

Chicago hands down, especially at nightime and with the addition of Millenium Park.

Its funny exclude your own city. I've heard from plenty of out of town people that Pittsburgh is spectacular when they drove through the Ft. Pitt Tunnels from the west and as soon as they hit the Ft. Pitt bridge - bam there is Pittsburgh and its 3 rivers and Point State Park (confluence of all three) right there is front of them. The view from Mt. Washington can take your breath away. Its like an aerial view of the whole downtown area.

America is boring. All of the cities look the same. Same characterless buildings, same stores, same people...thank go I'm out of here permanently in 5 weeks.

"Sexiest"??? Pretty simple IMO..Washington, DC with that big 500+ foot tall phallic symbol right in the middle...and I am not talking about the President, that's for sure.

President Clinton’s sexiest skirtline was…oh, wait a minute…you said SKYline….

Personally I love the NYC and Miami skyline.

Here are 2 pictures of skylines I came across

NYC!
Not only from the George Washington Bridge, but also coming in from the Long Island Expressway, as you crest the hill heading into the Midtown Tunnel or to the 59th Street Bridge; the sun is setting, the glow on the buildings - WOW! There she is - pure beauty and oh so sexy! My heart goes thumpa thumpa everytime!

Chicago's skyline is very romantic and impressive (old world meets new), but I also like LA's skyline. Especially at dusk. Being downtown in LA around dusk, all the buildings turn various, alluring shades of chrome, reflecting the colors in the sunset- some turn lavendar, some orangish, some reddish, etc. It's awesome.

Awesome...being surrounded by smog. Very nice.

Laguna, I'd welcome you up to see it sometime. It's beautiful.

Every big city has its problems with pollution.

I've been up there more times that I care to remember and its nothing great. Skyscrapers surrounded by smog so thick that at times you can't even see the mountains. And then all around you are built up areas and freeways-that is not beautiful

Seattle's skyline, coming into downtown on the Bremerton ferry right at sunset, with the orange glow on all the buildings, standing at the bow with your arm around your sweetheart. Can't beat it.

Worldwide, I'll go with Sydney, NSW. Hard to go wrong with the world's prettiest building and world's prettiest harbor in the foreground.

I think there are any number of brand-new skylines that would shock many posters here with the news that the USA is a third-world country architecturally these days: Shanghai, Guangzhou, Dubai, Kuala Lumpur, Singapore, and of course Hong Kong (with at least four times the skyscraper density of NYC).

Big City: Chicago
Medium City: Portland, OR

Sorry, I don't find Atlanta's skyline any better than other, plain American cities

I don't know about sexy, but St. Louis is certainly distinctive. You'll never mistake it for a different city.

My vote, for whatever it's worth:

1. Chicago with the natural beauty of the lake setting off stunning architecture.
2. San Francisco for the variety of architectural styles and the hills
3. New York for the sheer energy of the skyline
and...
4. The much ignored PITSBURGH. It's one of the most breathtaking experiences to drive through the Fort Pitt Tunnel and suddenly a magnificent skyline surrounded by three rivers appears!

Miami is another beauty. Atlanta's beauty doesn't lie in its skyline, but in the beautiful rolling hills, natural vegetation and pristine landscaping in the surrounding suburban areas.

San Diego. From Marina Park. At sunrise.

I'll nominate Bismarck, N.D., for simplicity. There, the state capitol, the only big building for miles and miles, is known locally as "The Prairie Penis."

I have to provide some support to PITTSBURGH as well, as an overlooked skyline. In general, I've been pleasantly surprised on my visits there by the downtown character. It often gets lumped in a group with Detroit, Cleveland, Buffalo, etc. as the "rust belt". Not at all.. a bit of a gem.

And if we're talking about the underdogs, here is a nomination for MINNEAPOLIS / ST. PAUL, which from the air is a case study in new and progressive (mpls) vs. old and distinguished (st. p). Also, the blue lakes and green parks mixed in make it very calming from a plane.

And another underdog nomination for Cincinnati, which has a nice mix of old and new, and also looks great on the riverfront at night.

Agree that my hometown, NY, is in a class by itself, and Sandi, you are so right about the view approaching from Queens, especially at sunset! It has always been my favorite view of the city and makes me so proud.

I'd have to say Hong Kong's skyline is also quite beautiful and impressive, with Victoria Peak in the background. I'd rate if # 2.
