This is a fun challenge that just popped into my head recently.The first drive in theater opened in Camden, NJ in 1933, and in 1958 the number of drive-in movie theaters reached their peak, at 4,063. As of 2013, there were only 357 left. Your challenge is to not have this decline happen, or at least not on the dropoff level of OTL, and have drive-in theaters remain at least semi-popular. How can this be accomplished?
