I saw a lot of things wrong with that video and a couple of things right. I think I need to watch more of her videos.
The way she was dragging the file across the chain was like fingernails on a chalkboard. Had to fast forward to where she was using the ever popular sawing motion to cut the tree. At least the tree went where they planned. I also like the way she was leaning into the cut when it bogged down. That helps.
Someone had a real brainstorm in the making of this! I'm glad no accident happened to such a novice while this was produced. Think of the workers with saws that had untimely accidents..with safety gear on...and they still succumbed injuries! Lots of exposed flesh there for that saw to kick back onto. Yeah, she looks nice, too.
