A friend of a friend used to have an annual weekend-long hog roast / beer blast at his place in north FL.
Had a 3 wheeler that was stored in the barn.
Of course the partiers knew about the thing, from association with the host or from previous parties, and would eventually drag it out and try to ride it (fortified by the alcohol, of course.)
It caused so many injuries that the parties soon became known as 9-1-1 parties.
It got to the point that the guy would take the spark plug out and suspend it from the rafters in the barn, and people would still try to get it down and ride it.
