Both Hopkins' English Department and Writing Seminars (Creative Writing) are among the best in the country. The latter may not only be among the best, but may be the best.
You should check these out, if you haven't already:

I know a few Writing Sems majors, and they like it. I've taken the introductory class in the department, and while I was in a Non-major section of the class (they separate us so as to not punish the people who can write), if was fun and interesting.
Also, you can go here:

and see what classes the departments are offering next fall, to see if any look interesting.
