Picture 11-2
Mike Haeg founded Mt. Holly, his own city-within-a-city, and has declared himself "mayor / chamber of commerce / justice-of-the-peace / town drunk." The other three citizens are his wife and two children.

Mayor Haeg's driver's license lists Mt. Holly as his address, and he publishes an online town newspaper, which is a work of art.

Here's a TV news video about Mt. Holly from April. Link
