A large music festival held in Mid June every year in Manchester, TN. The festival is located on a 700 acre field where patrons have the option to camp or sleep in their RV's. Bonnaroo is known for its popular artists, 24 hour music, and hippy lifestyle all guests can enjoy for four days. At Bonnaroo, drugs are just as easy to find as music is, which is very easy.
