Only California Polytechnic State University - San Luis Obispo seems to be known out-of-state; it is the most residential CSU and is more likely to be thought of as a “destination” campus than California State Polytechnic University - Pomona, which has about half of its students commuting from the local area.
NYC used to have “Polytechnic University” - mostly we just called it “Poly” back in the day in Brooklyn, then NYU bought it and started calling at NYU-Poly, and now it’s NYU’s Tandon School of Engineering. I think NYU was buying it the year D and I toured.
