Even in those states that do allow anonymous collection of jackpots, people will likely get a clue from the changes in lifestyle.

Not a problem, really, since I would also be making several firearms purchases for increased self defense purposes.

Yes, it would be virtually impossible to hide from anyone who knew you before. It would be rather obvious.
