As another Freeper suggested, use the money to open a chain of Christian pizza parlors.
Nope ... if the family is smart, they’ll keep doing the same thing they’ve always done and keep serving those people in that town of just a few thousand and go quietly about their lives, and wisely use their money, and not step out into foreign territory and overextend themselves.
That money should be for retirement, medical emergencies, some new equipment, kid’s education, and maybe a little fun thrown in there ... all of it done very modestly!
