Finishing up

In order to finish my mini ethnography, I need to interview more people.  I have a few done but I need more to make the paper more interesting.  I'm not sure what kind of research I can do for my paper.  There really isn't any information other than interviews and observations that would help me.  I'm a little concerned about using this as my subgroup.  I'm not sure how I'm going to be able to complete all the assignments if I don't have anything to research.  Yet I don't have a back up to write about so...I feel kind of stuck.  I don't know how I'm going to complete the annotated bibliography if there is nothing I can research.
