Slab City, built on an abandoned military base, is a decommissioned area in the State of California, with no electricity, running water, sewers, toilets, or trash pickup. Known as “The Last Free Place in America,” squatters live there off the grid, free of things like property taxes and utility bills. I recommend combining this with a visit to Salvation Mountain and East Jesus, both a few minutes away, as well as Joshua Tree, a two-hour drive.
