1st and foremost, i'd seek legal counsel on keeping my name out of the news.
then, seeking financial advice, put money into a trust fund.
take care of family with trust funds, so no one blows all thier money fast.
buying something of value like maybe a home, or small farm, that can be split into sub-divisions in the future.
buying maybe a pick up truck, and maybe non-descript cars, as to not draw attention to me or the wife with overly priced cars that make you stand out.
if a new house build, then certainly an underground shooting range, reloading room....with plenty of storage space for at least 10,000 to 25,000 rounds of all the ammo that i personally shoot. safe storage for primers, bullets, powders as well.
then maybe a few hand guns, of no extreme high dollar prices. in the end, unless one of a kind, they will hold no more value than any $1,000 to $2,000 gun would,
keep as low a profile as possible....
this can all be done with keeping ones head straight.
