I would fly back home (California) with my family and bring a friend or two, go shopping, buy more luggage to fit new stuff and go to theme parks. After I come back I would pay off the house we are living in, pay off my parent's debts, put money away for college, put more away for emergencies, buy my mom a new car, pay for my dad's surgery, get repairs done on house and more shopping. Finally, I would put the rest away for a rainy day.
