Should I go to Clemson or USC?

So I am a high school senior and have been accepted into both USC and Clemson for engineering. However I don't know which one to choose. My whole family has gone to USC and all of us including me are HUGE Gamecock fans. Also, my parents told me that because I have more scholarship money for USC, if I choose to go to Clemson then I wouldn't have enough money to pay for graduate school. However the catch is that I love Clemson's campus. I am a small town, outdoorsy girl and I don't know how much I will be able to fit into a big city. But then again I don't want my parents to have to pay more than they have too... Please help!!
