Make sure it is legal in your state and set a minimum number of tickets sold and keep a record of the ticket buyers so you can refund their money. I was involved in a raffle for a car that turned into a lawsuit over the “winner”...
Yep, interesting idea, but a lot of research required to be sure.
BTW, your reference to a mouthful of warm blueberry muffin really ruined by whole morning. I almost went to the tailgate of my pickup, but I couldn't pester you next week if I did that.
