Yes, actually, there were three campaign phases prior to that. We started with 441 global sites that were nominated, and then by public voting it went to 220. These 220 sites included one from each country. There were also some international sites. At that time, after the 220, the Bay of Fundy was still in as Canada's top site. Niagara Falls was actually in as an international site because the United States and Canada had nominated that site together.
Then, when the top 77 sites went down to the 28, you are correct that it was determined by a panel of international experts. I can name a couple of people on that committee: Federico Mayor, the former chair of UNESCO; and Alexandra Cousteau. If you recognize the name Cousteau, yes, she is Jacques Cousteau's daughter. She is part of an international initiative over a five-year period to raise awareness of world water issues. Also on the committee was a gentleman from the United States who is known as the silent walker—I can't even remember his real name—because he has walked across the United States four times over a period of 15 years to raise global awareness of environmental issues. He wasn't silent by the time he was on the committee.
So there were a number of international experts, some renowned, who actually evaluated the sites based on their international merits and their world calibre accolades.
