The only way to enforce anything in this sport is with the PORK GESTAPO.
I suggest that a rule amendment be added creating the Pork Gestapo. They will be volunteers, made up of overflow judges and the thousands of fans that sign up after watching an advertisement after every episode of BBQ Pitmasters. Their leaders will be crotchety bastards, never happy with anything but the black and white of the rules.
They will be assigned in force to the field of battle...popping their heads into every stroke of your knife, into every opening of your cooker. They will be tireless in pursuit of the rules, making sure each infraction is brought to the reps and organizer. They will find things such as the expiration tag on your fire extinguisher...or possibly the fact that between entries you didn't sanitize your table with bleach solution....
Yes they will find every single infraction you do...
Honor is paramount in BBQ. We used to hold it in high regard, yet the BBQ Explosion has brought glory hounds and honor less fools into our midst, all searching for a piece of plastic with a pig on top. Honor and integrity are alive and well in most of us...yet with popularity comes those that cheat, and they should be identified, vilified and banned, as there is no room for that in BBQ...create an organization to hunt down and root out the Beasts of BBQ
There is no answer. You can't enforce every rule without pissing everyone off. You just gotta hope the guy next to you believes in Honor, Integrity, and Fair Play.
