Rich and I were at Noah Purifoy Desert Outdoor Museum (http://www.noahpurifoy.com/joshua-tree-outdoor-museum)
It has an apocalyptic feel. I asked Rich for some words to describe it. He said:
junk
trash
vernacular
art
which I thought made a lot of sense!
I jotted down
sad
serene
boundary
portal
I might add
horizon

Looks like an interesting place. I like the way you present things.
