Where would a city of gold come from? The native americans did not seem to have any gold, venerate gold, etc. They encountered gold from the spanish. It wouldn't make sense for the spanish to build a city of gold. The spanish were not very crazy about Florida, it was a bad assignment. They were more concerned about getting the gold, getting to cuba, and then getting back onto spain.
what setting would be best to not discriminate this city of gold. A pi is not gonna cut it, unless I start digging all large automobile signals. Gonna need a bigger scoop.
