Frozen..........I hear ya experience. One piece of advice though. Think about getting them to sign some contract/liability/confidentiality agreement???
I have adapted the one I have used at all my home barbeques for our elk camp. Basically, it states that once they taste my smoked brisket, they can never move in to my house without my knowledge or express permission!!! They can not go home and beat their wives senseless for them not measuring up!!! They will not stalk me or hound me incessantly for my cooking techniques! And they can never, ever, under any circumstances offer "personal" favors in order to secure any of the leftovers!!!! Fan worship can be an ugly thing in an elk camp!
Good hunting!
