Great link.  While its from 2003, there is some good reading in the secondary links.

Referring to pre-Clovis civilizations...

If professional sceptics such as Haynes and Fiedel are right, then they are to be congratulated for maintaining their integrity in the face of a massive synthesis of false evidence. If they are wrong and/ or biased in their approach, on the other hand, then they would have successfully and vaingloriously held up the progress of American archaeology for three decades and artificially prolonged the life of the obsolete Clovis-first orthodoxy to around seventy years. With the ever-accelerating pace of scientific discovery, that would be an extraordinary achievement.

Time has proven the second scenario to be the accurate one, and Vance Haynes can suck a basket of pig dicks.
