What if a motorist coming by your farmstead clipped a pole, flipped, and was killed? 

Don't say it can't happen, because we all know it can.

I don't think the helicopter is less than 100' AGL in Rusty's photo. I suspect that most wire-caused crashes happen on the pull-up, not just the turn around. Usually a little more altitude is used for the turn itself to allow alignment for the next pass & a descent to pick up operating speed again. Speed is lost in a turn.
