The Nashville Zoo welcomed its one millionth visitor of 2018 on Thursday.
It's the first time the zoo has ever reached a million guests in one year.
The lucky guest was Kristyn Marci, who brought her two-year-old son, Asher, and 4-month-old son, Cohen.
The family got a gift bag full of zoo-themed gifts and a free one-year membership to the zoo – which should come in handy, since they visit about once a week.
At just 21-years-old, the Nashville Zoo is one of the youngest in the country.
In the last ten years, the zoo has averaged 8-percent growth each year.
