To All The Squirrels I've Loved Before
For those attempting to complete the To All The Squirrels I've Loved Before achievement there are also a few Deer in Chillwind Point (up near the road on the West side of the river; approaching Chillwind Camp). This location can be handier for Horde characters. Otherwise Deer can easily be found in Elwynn Forest, Teldrassil, and the Moonglade as noted above. "Other Deer" do not count towards the To All The Squirrels I've Loved Before achievement.
