So where would I post this?

Very well put tandkvd.
There is an amusing piece of folk lore relating to this subject; it goes something like this.
Many moons ago in Chablis, a young peasant and the daughter of a vineyard owner fell in love. One day the young lady's father and mother, both being a reasonable couple, invited the beau to dinner and to stay the night (in his own room of course!) at their chateau. During the night the young man woke wanting to relieve his bladder rather badly. Not remembering where in the vast chateau was the toilet, he had no alternative but to relieve himself through his bedroom window.
Unfortunately for his host there was a frost during the early hours of the morning, as a result all his vines were ruined. All that is, except one which he noticed had a covering of yellow ice! That's why ever since then, whenever frost threatens in Chablis, all the young men are expected to have full bladders every night ready to pee over the vines.
No, not really.
Ever since then, whenever frost threatens in Chablis the vines are usually sprayed with water (I say 'usually', because some put lighted braziers between the rows of vines).
So goes the story about the discovery of the benefit of spraying vines with water. Believe it or not - your choice! T
