Late-night entertainment channel Adult Swim is taking its show on the road with a five-week, 10-city cross-country tour. Its final stop: Portland Meadows on Saturday, September 17. Fans of the quirky network—in its 15th year on air—will have an opportunity to see unaired episodes, shorts, and never-before-seen pilots and specials on a 40-foot inflatable screen, for a one-night-only drive-in screening.

Adult Swim–which shares channel space with day-time alter-ego Cartoon Network—launched in 2001 with a stable of edgy programming geared to appeal to teens and young adults later in the evening. The Turner Network-owned channel currently offers a slate of syndicated programs such a Bob’s Burgers, Family Guy, and King of the Hill, but also features the popular Aqua Teen Hunger Force, Rick and Morty, and The Venture Bros. Ground-breaking anime shows Cowboy Bebop and Attack on Titan have also found a late night home in the network.

While this 18+ screening is free, RSVPs are required and may not guarantee entry. Movie munchies will be provided by on-site food trucks and early birds can even score a voucher for a free meal while supplies last.

Adult Swim is at Portland Meadows on Saturday, September 17. Check the Adult Swim website for more details.
