Troubadourable folk buddies Simon and Garfunkel once sang that "it's all happening at the zoo," before retiring from music to live out their days serenely basking in the reptile habitat. Get happening with today's Groupon for two adult admissions to the Jackson Zoo (up to a $16 value). The only zoo in Mississippi accredited by the Association of Zoos and Aquariums, the Jackson Zoo replicates the habitats of around 800 animals from more than 120 species. Visitors can safely view exhibits sprawling across 52 acres, such as the intercontinentally alluring African Savannah and Jewels of South America or, for closer examinations of familiar fauna, Wilderness Mississippi. The hand-carved endangered species carousel ($2 extra per person) is not only fun to ride, but also helps raise awareness of animalia through the mysterious power of steady rotational velocity.
