Thats why I don't buy tickets unless the jackpots get high enough that it's worth throwing away a few dollars for the chance.
I do the same, but it's completely illogical. I'd be thrilled with a $1M prize.
I work with a guy who buys lotto tickets all the time, but stops when the pot gets large enough for the media to start mentioning. He doesn't want to risk the publicity.
We're all weird.
