The Dallas Arboretum and Botanical Garden welcomed its millionth visitor for the year over the Thanksgiving holiday, and it’s the second year in a row that the garden has reached more than a million visitors. In 2016, the Arboretum’s millionth visitor came in early December, so it achieved the mark even earlier this year. Total 2016 attendance was 1,095,051. The Dallas Arboretum has had visitors from all 50 states and more than 90 countries.
