We have planted a lot of different kinds of plots over the years and for my money nothing has drawn them in the fall like turnips. You just need to be patient. They won't hardly touch them until you get a hard freeze, but after you do watch out, they will hit them hard. I have seen them walk right through the turnip plots and browse on native vegation before you get a hard freeze. Good Luck. Here is a picture of one our turnip plots.
