why insist this point? The man owning the collection is known to the hobby. ECS didn't find an untapped holy grail, but its no joke to the owner.
I've been in the antique car hobby now for over 15 years and I've never seen pictures or even know who this guy is. Its kind of silly to say that you know a place based on a few pictures that don't even show the name of the place or even have a location listed. Those pictures, for all I know, could be someone in the next state over from me. Again, without seeing any outside land marks, or being there in person yourself, there is no way to know or certain where this location is.
