No problem.

When we dug the hole we created a lip around the edge of the hole. We then laid a piece of plywood in there. It set flush with the ground and then we covered it with leaves, grass clipping and moss. So if they did walk in front of me they stepped on a board and not me.

And when they did they were close enough that when I did move......well lets just say that is when they realized it was not a fake sitting there.
