Boy, isn't that the truth. Perhaps you remember that Virgina had a unique holiday back then known as Lee-Jackson Day. It's now Lee-Jackson-King day, but in those days it was just Lee-Jackson day to honor Robert E. Lee and Stonewall Jackson.
Of course, that peculiar holiday was unknown to most people in the North, and the Virginia Board of Bar Examiners made use of this to give Southern boys a leg up on the bar exam. They would ask a procedural question that required you to calculate the last day on which a responsive pleading could be filed. The normal 21 days (or whatever it was) was calculated to fall on Lee-Jackson Day. Native Virginians, being well aquainted with the holiday, knew that the deadline was therefore extended one extra day; a non-Virginian wouldn't pick that up. The examiners then used the answers to sort out who was and wasn't a Virginian and acted accordingly.
LOL. Now why would some damnyankee fancy pants want to come down carpetbagging at the Virigina bar, anyway? Seems to me the bar examiners were just doing their civic duty.
Yes that was Virginia as late as the '60s and in The Valley for sometime into the '70s. Now that culture is mostly gone with the wind.
Soon it will be only "King" day.
RE Lee, the noblest and sublimest American of them all.
