Here in the bay area existed one of the biggest armored vehicle collections anywhere in the world, called the Littlefield collection. I actually didn't know about this until VERY recently. Unfortunately, Mr. Littlefield died of cancer a couple years back, and so the collection needed to change hands. So, what they did is they held an auction to sell off some of the vehicles to pay for a new museum for them in Stow, Mass, plus pay for their transport. I went and toured the place on the last day it was open to the public before the auction happened.
