I think they had to groom it.
The ice that looks so pretty, on the trees beside the trail was also on the trail. Before that, it was skiing quite well and I doubt anyone even thought of grooming up there.
But there have been a lot of people up there, after the groom that have never, or very seldom been up there.
IMNATHO, They deserve a chance to see it, too.
