The remnants are impressive, about a hundred buildings remain including the stamp mill (where the ore was crushed).
One walks around with camera in hand, looking into windows, some of the buildings can be entered, some have wire fences across the doors. In the church there is a pie tin sitting just inside the wire fence and people have tossed lots of coins and bills into that tin. One house with a bedroom seems to collect money too. Maybe folks figure the whores ghosts need a little help? I imagine the money goes to the non-profit Bodie Foundation that operates the little museum/information center, or maybe just goes into the parks operating fund (I'm guessing here, no clue really what they do with the donations).
The state owns and runs the ghost town park, but much of the surrounding land in the Bodie Hills is owned by the BLM (Bureau of Land Management, a federal agency), with some land in private hands. In recent years there has been talk about reopening gold mining in the area, and a petition was circulating in 2012 to get signatures to show support of NOT allowing such mining to happen in the Bodie Hills. You can find lots more info at the Bodie Foundation website and the Mono County Tourism website.
