Query: nostalgic memories and good time, grab some popcorn

I caught this documentary on PBS and happy to see it was available to purchase. This footage and information they have is very interesting and educational. Those of us who are fortunate to remember the drive ins will find this extremely nostalgic and fun. The next generation will find it very educational and probably feel jilted that they did not get to enjoy this great form of entertainment. I love how they show the history of how the drive in started and how this was a place to bring families in its heyday. I also loved how they showed "new advances" in sound systems, some of which were quite funny. It was great to see the "stars" of the drive in at it's heyday interviewed for this documentary, as well as the original movie trailers of drive in classics and as a special treat, there are concession stand ads there were used at the time of the drive in.
