Cartoon Network’s raunchy late-night comedy special Adult Swim is hosting a retro drive-in tour to show off unaired episodes, never-before-seen pilots and more crowd favorites throughout August and September.

The tour is making a one-night stop at Denver’s 88 Drive-In Theater on Sept. 10 as part of the national five-week tour.

An RSVP is required to attend the event, but admission is free. You must be 18 or older to attend and tickets are limited. To submit an RSVP request, click hereAn RSVP does not guarantee admission, so guests are encouraged to show up early.

Adult Swim will also host food trucks, free popcorn, concessions, trivia, games and prizes. There will be a limited number of free-meal vouchers handed out early in the night. Personal snacks and pre-made meals will also be allowed into the venue, but all bags, vehicles and persons may be subject to search.

According to the event’s website, cars can start lining up at 5 p.m., doors open at 6:15 p.m. and the show begins at 7:45 p.m. Car registration is at the Mile High Flea Market, just down the road from the theater. For additional information, go here
