Mila, Student in Fish, Conservation, and Wildlife Biology, "During the summer,the CSU campus is really quite beautiful. Though things are quiet, things are still open." Trisha, Incoming student, “It’s also nice to branch out academically.” Emily Hardegree-Ullman, Associate Professor, Physics, “I really like the summer session because the classes are a lot smaller.
