How many four-year North American universities and colleges have
sports teams nicknamed the "Trojans"?  Name them and the cities/states
in which they are located.

is that excluding high schools?

Yes, excluding both high schools and junior (two-year) colleges.  So
far I know of 11 four-year colleges and universities whose sports
teams are nicknamed the Trojans, but there are probably more.

Actually, you probably already have a complete list. The National
Directory of College Athletics says there are 22 schools with the
nickname "Trojans," and about half of them seem to be community
colleges (you can't get a full list online).

Ok, thanks.  Sounds as if I've got 'em all then...
