As a teeanager I was always told not to jump on winter evenings because the shadows of the floodlights on the poles make it much harder for the horse to judge the height of the jump. Is this true?
Never heard that one. but the other day we had a lesson and the sun came in the door and projected false ground lines for the jumps so Beau was wary or wold just leap and take off about 2 strides ahead!
