Just so you know.  You must have been looking in the mirror Lol    MDL   If this is by private invite only (including location) What is the fear? If L.E. managed to infiltrate they would be gathering info ie whose is coming and going and not necessarily busting at this event anyway. So with or without a bill board isn't the issue. If they are there without activity there could be future problems. My real question behind the question is. The M&G sosunds like fun but if there is say a 50%/ 50% split between hobbiests and providers and appointments are to be had I wouldn't want to be left with a room full of you horn dogs. Hobby safe and piece out :>)
