I'd do something positive with it - somehow helping my community, probably give half to the Salvation Army or another Charity that I know is in need. The rest, I'd invest in 10 year CD's (No, not the ones that play music) - Live for the now, plan for the future.
i would use it to buy every underground rap cd that drops for the next two months, because thats how much crap comes out yet they still complain when we dont buy everything. in two months 65g's would be gone. shits expensive some artists dont realize that.
