Raffle question

A few years back, I read about a high school (cannot recall where) that did a fundraising raffle that raised 1 million dollars for new fieldturf. They sold 10,000 tickets for $100 each and then had a big party and gave $600,000 back in prizes. Do any of you recall this? If so, I am looking either for the website that was being used, or a contact person to get some information.
Thanks for the help.
