Hollingshead, the inventor of the drive-in, got a patent on the design of semi-circular ramps, which was then thrown out as just a Greek amphitheater for cars, not patentable. If you can set up so the land slopes down to the screen, the ramps can be shallow. Also if the field is large and the cars widely spaced. If space is tight, you place the screen as high as possible and make steep ramps. All this of course is about sight lines over the cars in front of you.Carl Weesehttps://www.blogger.com/profile/12291898089206705608noreply@blogger.comtag:blogger.com,1999:blog-33929660.post-12541188522992471612013-06-17T21:54:08.165-04:002013-06-17T21:54:08.165-04:00Carl, this photograph shows a 'rolling' fi...Carl, this photograph shows a 'rolling' field which I assume is for better viewing.
