In California in the past several years there have been several attempts to change the laws for liquor sweepstakes, but it never comes close to passing. Politics is the name of the game.
The liquor sweepstakes have some quality prizes. One of the quirks in the states that have these contests is that the winner and companion have to be both over the drinking age for that particular state. This can be very annoying especially with the sports ones that I would like to take my son to.
Liquor stores are great places to find contest forms
