Selling Food on Ice?
Also wondering if you have to get permission from a lake association???
Heck, I may just get a $5 beverage license and try and sell soda, water, coffee and hot chocolate just to see how it goes.
You want to take a chance at doing it for profit without a permit it's your hide. The risk far outweighs the reward.
Most people bring their own food out anyway. Grilling out while ice fishing is all part of the fun.
