I, just me, personally, me think that the rules GB has set are really the rules we'uns have need to set for ourselves. OH, now I know that boys will be boys and in the smoker many will let things slide to the blue side, and, well, I must confess to that, also.
That may be ok, well, just maybe, however, I can also see that this attitude is still an influence on any which may be present and if we are completely honest, we have need of thinking about that.
Blessings
