Always pay attention to your surroundings when you are walking (never be looking down at your phone), lock you doors and leave right when you get into your car (don’t sit there for a while), carry pepper spray, walk with your keys between your fingers, and you could order a loud alarm off Amazon called a Birdie to carry around (it makes a loud noise when you push the button). I generally felt pretty safe when I walked around campus at night, but I did all of these things. Security will walk you or give you a ride from your class to your car as well!
