I think all we need is a checkline in the snow shed over there. Then if you take the route even if you cross the finish line it won't count. Unless we could put a jump their for fun instead.
Keep your mouth closed while chewing your food! That's ALL I hear.
A checkline would solve it, but generally physical barriers are preferred. Anyway, since it's an add-on there aren't any strict rules about such things.
Hey pal, I took an oath for justice! "In happy days or tightest tights..." or something like that.
