I remember when they use to open from dusk to dawn on the holiday weekends. I use to have a 'hippy' wagon and served beer from a keg out the back.
I use to 'rent' my car out to those who do not have a car. I would park my car in the drive-in so the 'renters' can enjoy the show. (Although I feel they enjoyed each other more.)
I would use the 'rent' money to play pinball in the arcades.
Those were the days.
