Avon Park, Florida

The claim: Air Force gunnery range, Avon Park has an on-base "correctional facility" which was a former WWII detention camp.

What it really is: The base never hosted a POW detention camp, and portions of the base itself has been declared land surplus over the years and has been sold off.

There is a prison there, but it's run by the Florida Department of Corrections, not the Federal government.
