The world was a VERY different place in 1977! Very different. We were just tourists looking at architecture - and mozaic tiles.
I guess. I am Israeli and was certainly there in 1977.
The concern comes because I’m a Cohen and a Hasid — I’ve been near the edges of the top of mount where our Rabbi said was OK, but candidly would be deeply concerned about wandering around up there.
That said, I’m also an engineer (aeronautical) and of the mind that the Temple needs to be rebuilt (opinions differ greatly on when this would be appropriate), and that would necessitate wandering around, to some degree.
