Lets say you were to win the powerball....
I would take the one time payout of $237,500,000 and live off the interest which should be around $490,000 a month (based 2.5% interest a year)
I'd have do some research as to where to store the principle. I wouldn't keep it in a American bank, not with the current trend of left wing politics in this country that doesn't want to view a person's cash wealth as their own property.
After that i'd buy a Superdome suite, a condo in New Orleans, and beach side lot in Puerto Rico.
