At the drive-up ticket window, the friendly young man is handing out these flyers. The information indicates which radio station to tune to for the movie sound. There's also an extensive selection of menu items at the concession stand. This is one of the very few places that will still sell a "cup of ice" to their patrons. Most others have signs hanging in their concession stands proclaiming "WE DO NOT SELL ICE!". Did you read the flyer text yet? Don't believe the note on there about "all radios since 1957 won't drain your battery". Although I've seen that statement on a few drive-in flyers, it is false. Modern cars are loaded with accessories that WILL drain the battery if the ignition switch is left in the accessory position. For best results, during the movies, start your car every half hour or so to recharge the auto battery. Most drive-in patrons know to bring a battery-powered boom box for the sound.
