I don't play the lottery. Nearing 70, I've never once bought a lottery ticket of any kind for myself. (I -have- bought tickets for others upon request a few times).
But... if I DID buy a winning ticket like this one -- the LAST thing I'd do is "go public" with it.
I'd put the winning ticket somewhere safe, then search for an attorney I could trust. I'd then have him act as my proxy, and place the claim with the request that my name NOT be made public. I believe the lottery agencies will respect one's wish to remain anonymous (I could be wrong). Then I'd produce the ticket. I wouldn't even visit the lottery office myself. If a signature is required, I'd do that by mail.
I'd take the payout (all at once), have the taxes paid off, and have the attorney deposit the check into a bank account (perhaps more than one).
And then... I'd keep my mouth shut about things.
