what would constitute "proof", Sparky?

Retroreflection is accomplished by having three mutually perpendicular reflective surfaces forming a hollow corner. Natural cubic crystal formations can easily develop hollow corner retroreflectivity. So, to show that it was the Apollo lunar ranging experiment, and not a natural crystal formation, you'd at least have to have before and after shots showing the difference.
