The claim: WWII Japanese internment camp
What it really is: Yes, there was a Japanese internment camp there. All but one of the original buildings there were torn down or removed, and the site itself is now described as a desolate and lonely place.
In 2006 the site was named a National Historic Landmark. Also in 2006 President George W. Bush signed into law H.R. 1492 granting $38,000,000 to preserve and restore the site and nine other Japanese internment camps for historical and educational purposes.
