If I won 250million dollars: Id leave the state at least, then look for a big piece of land in Wyoming..at the foothills of the rocky mountains, iv always wanted a big ranch.
id give my mom, dad and sis whatever they wanted (Sky's the limit) lol
i once heard that when Bill Murray made his money, he gave his mom a credit card with 100,000 limit...i like that idea, so id give them that too, so they don't bug me for money

that way they can spend what they want (within limits) lol
id set up a trust fund for all other family and close friends..enough for them to be secure in life
then Id travel the world!! just look around, see where i want to keep time at, and id buy small flats in thous city's or towns...not many just a few
the hardest part would be finding a bank that would secure the money
then id also set up a trust for myself, something that would grow even when I'm gone, and a foundation that would help thous that i wanted it too
PS: also have a big party for all of my friends from GH!!!! lol
