Connecticut has strict regulations concerning raffles of any kind (as do most states I would think) and I strongly urge teams to follow these regulations when thinking of holding a raffle as a fundraiser (this includes the ever-popular raffling of door prizes at pasta dinners and pancake breakfasts). You don't want to be fined as a result of ignoring the state laws. It will defeat the purpose of holding the fundraiser in the first place!
