Right outside Goldfield, Nevada is this bizarre attraction, the International Car Forest of the Last Church.  Constructed starting in 2011, there are over 40 old vans, limos, sedans, trucks, & school buses in colorful graffiti planted standing up while other vehicles are stacked on each other.  Signs point to this being the world's largest national junk car forest.

The town of Goldfield itself has many properties w/ yards full of junked vehicles, but I guess standing them up suddenly makes it contemporary art...
