I was wondering myself if they knew where it was buried. Or if they had some kind of marker for it
Well, there was some kind of stone marker and metal face plate — saying that there was a car buried and a time capsule there, too — but — it wasn’t clear exactly where the actual vault was.
So, they did have people doing some kind of “ground search” trying to locate the vault (some kind of hi-tech equipment involved). It was on the news that they didn’t know exactly where it was at... LOL...
