Does anyone have it or know where I can get it or if it even exists or someone who could tell me what the attraction was like because i'm very curious.
1. The Extinct Attractions Club has a DVD of ATIS.
2. Atommobiles.com has several (soundless) video clips, as well as an upcoming full-length virtual ride-through.
Those are the 2 I know of as well, but haven't taken the plunge to buy one. There was a very detailed history with lots of photos in last summers edition of The "E" Ticket magazine available at http://www.the-e-ticket.com/
Anyone interested in Disneyland history should check out this publication; it's worth it just for the arial photos of the park. I'd known of it for years, but when I finally saw a copy, I immediately started ordering back issues.
