Hack became obsessed with motorcycle gangs after he bought a used Vespa scooter in 1967 and fancied himself quite the hellraiser. He and some other “biker” friends watched Marlon Brando in “The Wild Ones,” got excited and tried taking over a small town. They spent the weekend in jail until one of his friend’s mother bailed them out. The Vespa was stolen a few weeks later by a gang of roving bicycle thieves.
