Like many people in the eastern USA today, we are having torrential rain today. After being gone from the farm running errands for a few hours, I saw that most of the sheep were under their shelters, but one ewe and two rams were not where I expected them to be. I found the ewe trapped in a tangle of vines growing along a fence. She had been flirting with the rams on the opposite side of the fence. The rams were not trapped, they just had higher priorities than not getting completely drenched.
I got out the Strongarm (420HC, rated 8 for corrosion resistance by Larrin), but after cutting a dozen or so vines, the ewe still could not move much. I finally found a vine about half an inch thick that was across her chest, buried in her fleece where it was not visible. I cut that vine, and the ewe ran over to a shelter. The two rams looked at me accusingly and wandered off to some trees.
Sorry, taking photos was not really practical.
