Well, I'd definitely get the lawyers and CPAs to make sure that bag is secure and protect my family's privacy as much as possible. After that...

• I'd hire a high-end architect to renovate my home.
• I'd hire a personal trainer to help my family get really fit.
• I'd buy a big vacation for our extended families.
• Buy a less family-friendly vacation for our friends.
• Hire a therapist so I don't go insane.
• There's a small, vacant movie theater in my town. I'd buy it and get it up and running again.
