Austin City Limits Festival attendees can no longer bring bags larger than 18 liters or roughly 1,000 cubic inches which is 10 inches wide, 10 inches long and 10 inches deep, organizers confirmed Friday. The new policy comes in wake of events at a Las Vegas music festival that sparked conversation around more robust festival security. ACL organizers suggest concert goers do not bring bags larger than a typical drawstring back pack. All bags are subject to search. Friday is the beginning of the first two the consecutive weekends of ACL Festival 2017.  For more information regarding prohibited items, visit the official ACL Festival website.
