I'll fess up... at a school "car Show" day.
Wasn't part of the plan, but a careful recce and much contemplation:

Two being the magic number, no engines. Note how the hood and roof collapsed to act as guides. The exit was a bit rough, do it on the lawn if you decide to follow through.
The local jeep club spent the day doing unspeakable things to the cars first, as did one of the local trials motorcycle guys that manage to crawl over ....anything. Consider contacting them to add to your show.
And maybe a helmet.
Enough for now.
