NEW YORK - All you need is a dollar and a dream and you could be the next mega winner in the Mega Millions. 

The climbing jackpot is already the game's fifth largest ever, and Brooklyn residents are among those crossing their fingers. 

Many people have already started thinking about how they'd spend the big reward if they won. Many would retire, move or make a big purchase. 

The luck of the Irish could be lucky for New Yorkers. Lottery officials say that nearly 100 Mega Millions players have cashed in on $1 million or more during the month of March since 2009.
