This is one of the most rusted out abandoned vehicles we've ever encountered. The incredibly rust-laden late 1960s Ford truck was spotted near Kahaluu, Hawaii, by Jim Prueter. Prueter said he was told by a "reliable individual" the rust was created by the huge amounts of acid rain caused by the active volcano on the big island. No reason to doubt that analysis — the proof is in the Ford. (Photo by Jim Prueter)
