For a little while each February, the sun reflects on little Horsetail Falls in Yosemite Valley, which make the falls look vaguely reminiscent of the old Fire Fall of yore.
The NPS was so worried about crowds of photographers this year, that they set up a reservation/permit scheme for parking spaces.

Well the crowds show
ed up.
Horsetail Falls didn't. No snow=no water=no firefall=no brainer.

A Ranger we know there reported it took three hours to drive the 14 miles into the valley because of the traffic.

I can only suppose that since the NPS thought requiring parking reservations were necessary for the "fire fall" event. then the photogs assumed that Horsetail Falls must be running.
Either that or the NPS figured crowds would come up anyway to trample the meadow and look up at where Horsetail Falls would have been.

A curious situation.
