I had a encounter once. There was a baby deer in my driveway so I was curious and went closer thinking it was lost?... if I tell you the sound that came out of the mothers mouth about 50ft away scared the snot out of me. She came out of no were. I slowly steped away and went back inside my house contemplating going back out with a wepon of some sort lol but I didn't.
We have frequent deer visitors daily in our location.
No problems with deer attacks. There are many goose and wild turkeys attacking (they hide just before the season because they become smart and can read the hunting regulations) that randomly get aggressive.
