the drive in an hour south of here was just closed down last year.

the one near me in my childhood home of Omaha had not only mini golf
but a short-lived trampoline recreation place. they would dig a pit
and put the trampoline down in it...so the bouncing surface would be
at ground level and you would be less likely to fall DOWN off of the thing if you bounced off. i think there were some injuries any way,
and those types of businesses were never open long.

here is a page with info on california drive ins

California's first drive-in movie theatre opened in
June of 1938 (there were less than 15 "auto theatres"
in all of America at that point). Within just ten years,
another 43 drive-ins had opened up and Calfornia was
on its way to becoming one of the top drive-in states.
