Just thought that I would add my two cents, pun intended, to the metal detecting discussion. Another solution to omnipresent metal detectors on military sites might be to recruit them. They are interested in the past, though for different reasons than many of us, and they have time, something in short supply. Garry Wheeler Stone at Monmouth Battlefied State Park in New Jersey has recruited and re-educated a whole contingent of metal detector afficianados. Working together they have been able to present some fascinating insights into troop movements during an important Rev. War battle. While this solution is obviously not applicable to all sites, it has worked well here, and brought two disparate groups of people with a mutual interest in the past together, to everyone's benefit.
