The festival is working closely with state, local and federal authorities to ensure that all festival-goers have the safest experience possible in a park packed with people. The festival is expecting to see 75,000 people per day.
In light of security, ACL has a strict bag policy.
People are only allowed to bring small purses, totes and drawstring bags. Those bags may not exceed 14 inches by 11 inches by 5 inches in size. Bags with multiple pockets will not be allowed at the festival.
Hydration packs are allowed, however, the festival said they must be empty before you go through security and they may have no more than two pockets in addition to holding the water reservoir.
