This is the only day of the year, when there is absolutely NO traffic on any mountain road or highway. In 2 hours since dawn, not a single car, except one neighbor. Usually, a couple of hundred, all over the peaks, every few hours, rain or shine.
They are sleeping it off, revels end before sunrise.
Those in rotation or "higher up" get to do it on the day of; most others, do it the day before or after, depending on the coven and their schedule.
So, if you know someone who conveniently had to be out of town or away between the 28th through the 31st, THEY ARE COVEN and are WITCHES. Which means, blood, orgies, the lot. Yes, even that dutiful little wife of yours who just had to go home to mama, or a camping trip, or, or, or, is being corn holed by dozens of fat guys.
Just how it is.
