If you are looking at colleges for journalism, look at Arizona State. They have a top-rated journalism school, and has some decent merit aid.
You may also want to look at U Missouri. Its journalism school is actually one of the top ranked journalism schools in the country - every list includes it in the top 10, and it is often #2 after NWU. It has decent merit aid as well.
Georgetown should be on your list, as well as George Washington (but run NPCs for GWU). I think that somebody already mentioned Emerson to you.
Does your high school send students to Posse? You’d have to be nominated by your counselor and then your school, though.
