And there is no true scientific basis for banning feeding. Deer are social animals. I see more contact with the licking branch near one of my plots (which also has a feeder) than I ever do on a particular square foot of dirt. Literally every deer that can reach it, licks and rubs their face on it. I have also seen fawns stand on their back legs to try to do the same.

And they lick each other, regardless of the time of year or presence of bait/food. Banning feeding won't change that.
