How to build a deer fence

Deer are a problem most everywhere in this country. Everyone has heard the horror stories about deer coming into the garden and eating the entire thing in one night. Here is a system that may keep deer from coming into the garden and eating all your vegetables. Polytape is placed in front of a barrier, in this case a fence. It has been placed about 3 feet away from the fence. The deer as they come into the area can't tell the distance between the polytape and the barrier, the fence, therefore are afraid to jump over it. Deer don't have a good sense of depth perception, thus this is a good way to keep deer out of the garden.
