My yard would be literally impossible to fence completely without also installing multiple gates. Luckily, all the large busy roads in the area create a sort of car fence, a little like living on an island. At any rate I've only extremely occasionally seen a deer walk through. But rabbits, voles, squirrels and other rodents are a bane here. Luckily, they are mostly disinterested in Daylilies ( anyway, the rabbits) which is what got me into fandom in the first place.
