Eric, I am thinking of putting up some vinyl stock fence and if I do I will drill holes in the posts to pass a hot wire between the lowest and next to lowest horizontal "board." My fence consultant (friend with 40 years of experience with a sideline of FENCE CONTRACTOR told me that would convince stock not to push on the fence to reach over for a delectable mouth full of the grass that is always greener on the other side.

I should imagine that you don't have to have the wire secured to the rail and that it could be run lower to the ground if desired. A hot wire run this way is hardly seen unless you are up close or look carefully.
