First, let me just say that if you live in Arizona, you really should sign up to receive the RSS feed from the ABC15 Smartshopper. Here is the link for today's deal. From there you can sign up.
The deal is that the two local drive-in theaters (Scottsdale and Glendale) will be offering free family movies on Thursday night, September 17. They will be showing "Up", "Star Trek, The Future Begins" and "Night at the Museum, The Battle for the Smithsonian."
Gates will open at 6pm and movies will start on 8pm.
