Depends somewhat on the year, but on my place I get the same results as you. I have clients 20 miles away in all directions that have them get hammered. Some deer like them, some do not. Also I think they are better in the north than the south, but some deer like them in the south too. It does take a good hard freeze to sweeten them up.
You might want to try daikon (aka tillage/trophy/groundhog) radishes or a forage rape, both are more palatable than turnips. All brassicas are reasonably close in preference, but these do a little better.
