yak:Great article Matt!
One thing I would add from experience:
An EP told me that only one side of the carapace needs to be legal. Until that day, being right-handed, I would hold the lobster with my left hand and measure it from its right eye socket using my right hand.
Now, if the right side measures a hair under, I try the left side. Sometimes it'll end up being a keeper.
There is always some leeway on the cops part, this sounds like one who wants to educate and not write tickets. You might however run into one who says it only needs to be short on one side for a ticket. (statute only specifies length and landmarks, not which side, and doesn't account for asymetry) when in doubt let it go.
