There is still lots of stuff out there owned by folks that aren't on the Internet or wish to keep it on the down low for security and privacy reasons.
I know a guy that has a regular 68-1/2 R code Mustang fastback project stored on the side of his mom's house. The family isn't on the Internet, and several trees would need to be cut down to get the car to the front yard.
Very cool car indeed! This was in the "Rare Finds" of either Mustang Monthly or Muscle Car Review just a couple of months ago(I read both magazines and don't remember which one it was in). If my memory is correct the magazine article also stated there was a Boss 9 sitting in the back yard.
