I think you misunderstood what I was saying. There are no "drunk driving" stories. I freely admit they mostly made the drunk driving stuff up out of thin air, although from time to time it has showed up on message boards and fan sites as an excuse - for example:

However, the "roaming gangs of teenagers" and "general drunken and rowdy (unDisneylike) behavior" claims have been around forever (since the island was made free to the public) as excuses to close up Pleasure Island.
