According to Wikipedia, this event is traditionally held at the Washington Hilton. There are so few photos of this dinner (compared to other formal evenings such as the Whitney galas) and it drives me nuts because I loved what I saw of this dress. The shoes added that little extra something with the criss cross straps and the ponytail was a great look for her.
Since the president attends, I’m sure security is extremely tight, so not just any photographer can get in. There aren’t that many great shots from the 1999 dinner either (at least not full length where you can see the entire outfit).
In this gallery, there are several HQ close-ups and the one shot that shows them walking in can be made bigger. The man who took some of these has a Flickr account and I recall him telling a story about the kiss photo. Apparently John staged it so this man could get a good shot to sell. I need to search for it again as it was an interesting anecdote.
Note: photos 9-10 and 17-19 are from http://www.celebrity-photos.com. He is the one who had the story about John and Carolyn kissing for one of his photos, although I’ve yet to find it on his site. It’s also attached to a Flickr account, and I think the description might be on there somewhere.
