[TowerTalk] Bye Bye Deer

[Pete Smith N4ZR]

To the best of my knowledge, nothing really works except fencing.  A 
neighbor across the road has an open permit that lets him shoot as many 
deer in his resident herd as he needs to keep them from destroying his 
corn crop.  for years, he had a propane cannon rigged to fire 
periodically, but after a few weeks the deer just discounted this.

Local vineyard.s have gone with 8-foot-high fences to protect their 
grapes - may be the only way
