Stream jumping

Not really a Back-Blip. I uploaded this Monday & obviously forgot to hit the "Publish" button. Only noticed next day but not important as a miserable photo but I wanted to record Luna's first leap across the stream at the bottom of the horse field. Photo was a split second too late but she made the 2m though her hind legs just touched the water.
Luna seems to be incredibly sportly but as comparison we only have Flash who was always "heavy boned". His reactions are lightning quick (eg as goal keeper when playing football) but he was never a big jumper or climber.
