I have my garden fenced in too. 48", 2x4 mesh. Deer can hop over it, if they really want to. There's so much food elsewhere that they haven't bothered to try. Ditto with the turkeys, who tend to be very destructive taking dust baths. We do have moose and bear, which would both go right through the fence if they wanted to. Of course any animal that isn't kept out by the fence is automatically classified as a nuisance animal destructive to property and crops and fair game for termination.
