Slab City, California, is known for being one of the last lawless places in the U.S., or so the slogan goes. The town is a collection of misfits, hippies, the homeless, and just regular people looking to get away from civilization. The town, which is actually unincorporated, charges $30 a night to stay there, or visitors can bring their own RV. Apparently, police also occasionally patrol the area, meaning it's not entirely lawless.
The community in Slab City also regularly gets together for social gatherings and things like karaoke. If you plan on stopping by during your next road trip, then be prepared to embrace your inner free spirit.
