Deer fence which seems to work; lifted from Youtube
by Roberta Bogner
A Youtube video entitled "Innovative Deer Fence" stated that deer have no problem jumping upwards, but are intimidated by having to jump both vertically AND horizontally. So this guy tilted his fence posts out at a 45 degree angle. I copied his design using plastic chicken wire and wood, and after a couple weeks, still have unscathed fruit trees.
