Seek, and ye shall find. Only thing is, we weren't seeking... for this.
Driving down a back country road in eastern Iowa... out in the middle of nowhere... we stumbled across a metal Moai. Like you would see on Easter Island (only the ones on Easter Island are stone, not metal). Just sitting right there in a field of grass. In Iowa.
Talked to the farmer who owned it. A friend of his made it. The farmer was quite proud of his Moai, and was clearly excited to tell us all about it. We had a great conversation with the guy, and he invited us back anytime. He says it looks great in winter surrounded and covered with snow. I think we'll go.
