Dan, I'm even more of a cheapskate than you, blowing a WHOLE DOLLAR when a jackpot gets huge. Thinking about it though, winning a prize that large could be more of a curse than a blessing.
Get out you calculator and read the odds...then imagine each of those chances to hit all the numbers right as one inch of highway...how many miles is that? From Seattle to L.A.?
Imagine yourself driving that distance, and tossing a gum wrapper out the window, having your gum wrapper falling on that one inch!
Still, somebody wins once in a while...and a few bucks spent in order to fantasize for a few hours isn't really a sin, is it?
