Speaking of electric fences and deer, there is a fairly new development in deer fences that I've watched this year, in person, and am very impressed. You put up two fences, a few feet apart. The inside fence has two strands of electrified wire, not really high. The outside fence has one strand and is positioned in height between the two inside strands. It messes with the deer's depth perception and seems to be almost 100% effective at keeping deer out. I'm going to build one this winter to enclose a permanent dove field.
