I’m pretty sure UNC/Chapel Hill has some ballet opportunities, though I’m not sure how rigorous they are. There are also several pre-pro places to dance in the Chapel Hill/ Raleigh/Durham area as more of an EC …(not as serious as CPYB, though, but at least an outlet for your skills. ) Have no way to know how the scheduling would work with your required coursework in engineering. Also, University of Indiana and Florida State University (and I think University of Arizona or Arizona State?) have highly regarded dance programs including ballet, but don’t know if non-dance majors are allowed to do much. If you went to University of Pittsburgh or Carnegie Mellon, maybe yo could take ballet classes at Pointe Park University’s dance program or the school of the Pittsburgh Ballet Company. It would certainly take a lot of travelling and juggling, if it is at all possible!
