In reply to: USA still has to cut their host sites to 10 posted by miamioh_irishfan
Both cities had the same group. Also, DIA is better for overseas and NA connections (particularly Mexico) than a good number of others.
I'd like the following:
New York City
Los Angeles
Atlanta
Dallas
San Francisco
Miami
Seattle
Denver
2 of Boston/Philadelphia/Washington, D.C.
The Seattle matches were on a Thursday night (5:30 and 8 pm PT), while the Denver matches were on Sunday (1:30 and 4 pm MT).
However, I think your suggested group of 10 is reasonable, even though you have no Midwestern cities. Some of the cuts will be more difficult than others.
Mexico v Canada was arguably a more interesting match to El Tri's fans in Seattle than Mexico v Martinique was to El Tri's fans in Denver. Having been at the matches in Denver that day, I'm certain there were more Canadian fans in Seattle as well (although admittedly likely fewer than would have attended if the match was on a weekend).
The broader point I was trying to make was that Denver's interest in international soccer relative to Seattle's (or other cities' for that matter) shouldn't be measured solely (or even predominately) by interest in their respective MLS clubs.
