[IndispensableDestiny]

The drive-in experience requires a front bench seat.

And a back bench seat...

We used to go with four people in my pick up truck.
Park in the back row and turn the truck around.
We had an old car seat in the bed, A cooler and a couple lawn chairs.
Plus a pair of Jensen speakers in wooden boxes I made to set on the roof of the truck.

Then sit outside watching the movie drinking beer.
