Gambling - sure, it can fun, but it's also illegal. (unless your in a properly regulated casino, of course) Which is why we think of underground card games as sinister mafia-run operations where the stakes are high, the cash is real, and the punishments are tragic. But what about a Wednesday night Euchre game at the Senior Center where old people pay $1 to win tubs of mayo - is that illegal gambling? You bet your ass it is. (according to the Indiana Gaming Commission, that is.)
