Form an LLC or foundation. Let the lawyer for that cash in the ticket so I can stay anonymous. Hire a three man team to manage the money, none of whom know each other, and periodically have an outside auditor look over their shoulders just to be sure the numbers still add up. Move to Texas or another no state income tax state for 90 days before cashing it in to establish residency. Once I got the money (lump sum), I would split it 50-50 with my wife. That way however much she chooses to give to family, church, charity or whoever is up to her. Same for me - if I buy something stupid expensive, it's not coming out of her pocket. Should reduce money friction within the family considerably.
Pay off everything. Buy a couple of daily driver but nice cars. Buy one or two more toy cars. Build a home to my specs, probably using the Taliesyn architects who do things Frank Lloyd Wright style. Get a nice loft to live in while that's going on. Travel. Eat well. Use a personal trainer to get and stay fit after eating well, lol..
I'm not sure where I'd wind up living. I'd probably stay based in Birmingham, but travel with an eye toward finding another place. I've always said that if I ever hit the lottery I'd get a place overlooking Lake Austin, but that's negotiable. Perhaps live six months in two different places, rotating to comfortable climates. In the meantime live a life that pleases me. Play angel for selected charities, see shows and concerts, be good to my friends and family.
Oh, and fork continuing to work. I have a few co-workers I'd drop some money on, but I'm old enough that it would be immediate retirement and disappear.
