One funny story...In 2013 I attended the National. I entered a cut comb...about a perfect specimen. Unfortunately my entry was disqualified as it was in the wrong style container. The rule was a standard comb honey container with a clear cover. I had that covered and the judge said I could use my "American" container. I asked the show organizers about it afterward. At my request they changed the rule to "A standard British comb honey" container. That was a good outcome as the rule was clarified.
The funny part...The head steward handed me a shopping bag...I should have known something was up by the grin on his face. Inside the bag? Half a dozen "British" comb honey containers with clear covers. I thoroughly enjoyed the joke.
On another note...I've been asked to attend the National this coming October for several presentations. Color me excited. If you do attend this year, I would enjoy meeting you.
