I came across this rusty monolith in a funky carport on the island of Lanai. I'm thinking that the front end that's most exposed to the sunlight and rusty dirt has changed color over time. It obviously just sits there year after year and the brighter green of the door is just deep enough into the structure that it has retained some of its former glory. I definitely love old cars and trucks, but haven't painted too many for some reason. Maybe I am turning over a new leaf, and since green is my favorite color this was a splendid place to start.
