More likely than not, no, I wouldn't.

I would follow the lines, and hopefully I would have a map of the area and a good guesstimate of where I was so I could go in the correct direction. The power line cut would be semi cleared, make for faster movement, and there is always the possibility of someone living right along it.

With my luck, I'd chop down a pole, it would spark, start a forest fire, and Smokey Bear would appear and beat me silly.
