Our last drive-in, The Twilite, closed in 1991.  They ran a big monsterfest movie marathon the last weekend it was opened, showing all the great old monster movies from years ago.  I remember going there as a kid with my parents to watch the latest family-based movies, then later as a teen to catch the latest slasher/horror flicks......there was an added sense of suspense/being scared sitting there in your car with all the windows down while watching the scenes on the big screen. 

We don't have an original A&W left anymore either, but when our's closed, the manager bought it and the rights to continue using their recipes/food/drinks.  He had to change the name to Old Town Drive-In, but he still has a prospering business going there.  And yes, you can still get the baby mugs of Root Beer too!   I miss seeing the familiar orange, white, and brown lettering on the mugs though!
