The cabbage family doesn't make it through the growing season unless I station myself or the dog in the garden to discourage moose. Last time I tried brussels sprouts and cauliflower, which is great when fresh-picked, I went out with sack and knife and found bare ground where just hours before the crop was just right and ready. Clipped off at ground level--all of it.
Moose? Well, moose would certainly be a problem.
