I went to Rutgers. I transferred there from a community college, and similar to you, I had varying theatre experience, and realized I wanted to stage manage when I was thrown into it at the community college. It's a great program, because you end up with a BFA in Production, but if you emphasize in stage management it's basically a BFA in that. It's almost nonstop stage management, but in addition to that you have to put in time in all the shops, and they have small classes. I had to take everything from ligthing design with MFA designers, and costume construction, prop construction, acting...and the SM professors put as much emphasis on those courses as on the stage management assignments because they are things that would only help you in the long run as a stage manager. Tom Kelly taught there (at the time), and after him a another top stage manager was the SM advisor, and there's tons of great people there. You probably would realize in the first couple years if it's not for you, and the best way to find out is to go somewhere where they throw you right in. I did, and realized it defenetly WAS for me, but I know some people who did change their minds. And you CAN change your mind if it isn't, but at least you'll be well rounded in theatre production, and you might find your niche in the process.
