My cousin got caught doing this down in Montgomery Alabama back in the 90's. He spent a good bit of time away for it too Granted he had prior charges for gambling and bootlegging that may have affected his sentence.

It would take a while to get caught depending on how many people you got coming in and how much is being dropped nightly or however long you're holding games. The more money and people that shows up the higher your risk becomes because of sour ass people mad because they lost this or that.
