Can you describe the slabs in your words?

"The Slabs," are the remnants of a demolished Navy air base that has become home to a community of drifters. It's like a huge counter-culture hippie type of community. Many want to drop out of the middle class grind into a sort of bohemian camp.

"When McCandless arrived at the Slabs, a huge flea market-swap meet was in full swing out in the desert. Burres, as one of the vendors, had set up some folding tables displaying cheap, mostly secondhand goods for sale, and McCandless volunteered to oversee her large inventory of used paperback books."
