I would like some inspiration? :)?

I am thinking about making a design for my high school. i attend Wallenberg Traditional High school in San, Francisco. Im only a freshman, and im still not sure what we are really known for, i want the design on the hoodie to represent us, not something just random. I mean our mascot is the bulldogs, but i feel like there is something more then that. We have very artistic people in our school, were athletic and diverse in many ways. and of coure for skateboarding. but how can i put that together in a design? help?
