The Silverdome Drive-in in Pontiac, Michigan closed on July 13, 2011, according to a post on the theater's Facebook page:

To Our Valued Customers:

On behalf of The Theater Group we would like to thank you for the support that you provided to the Silverdome Drive-in. At this time we regretfully announce that the drive-in will no longer be operational effective immediately. This season Triple Sports and Entertainment, the ownership of the Silverdome, took over day to day operations of the theater. After many behind the scenes issues we have decided to no longer allow the Silverdome to use the drive-in equipment.

As guests and supporters of the drive-in we want to thank you for your support over the years and understand that closing the drive-in was not easy as it brought much enjoyment to members of the community. We are currently exploring other options for a drive-in within Oakland County and hope to be able to return in the future with another venue for local residents to enjoy.

We will continue to update this facebook page with information and updates about our search for a new location. Once again thank you for your support of the drive-in.

Sincerely,

The Theater Group Management

Those looking to enjoy their movies under the stars will need to do some traveling, as the nearest drive-ins to the Pontiac area are the Compuware Arena Drive-In in Plymouth (~21 miles) and the US 23 Drive-in Theater in Flint (~30 miles).
