Oh 1 other thing I put down there for my slave to spend some time down there alone safely, that may be a thought for some of you. I picked up a baby monitor at a garage sale awhile ago. leave her ungagged turn it on & clip the recever on my belt & do whatever I need , if she gets in trouble I am only call away, where ever I am. I was quite impressed at the range of it, can even hear her when I am on the tractor mowing the lawn.
