The funny thing is that there was SO MUCH native American presence in Indiana (aka: land of the Indians) that virtually EVERY construction site or road building activity turns up artifacts. If they had followed the law and stopped construction and notified the authorities every time an artifact was discovered, I-69 would have NEVER BEEN COMPLETED through southern Indiana, and most everyone I know that built a house would have had to stop constuction due to artfacts being found at their "archeological site (aka: basement)". It is a stupid "feel good" overreaching law that came out of Bloomington (nuff said).
Better yet, the academic archaeologists don't even bother to follow the law either.
