All you need is two dollars and a dream that defies odds so incredible that you'd have a better chance at winning the presidency.

The nation is going Powerball lottery crazy again with the jackpot having reached $500 million on Tuesday and destined to go even higher by the time the winning numbers are drawn at 10:59 p.m. ET Wednesday.

Nobody won the drawing last Saturday night, which was a mere $325 million. Now that it's $500 million and counting, you can bet everyone and their brother and their brother's brother's brother will be buying tickets, guaranteeing long lines at some lottery stations.

Since it's practically a national lottery, Powerball is available in 42 states, the District of Columbia and the Virgin Islands, where the winning ticket holder may be headed for a long vacation after collecting that fat, fat check.

Oh yeah, the odds of winning are still 175,000,000 to one. So dream really hard.
