Anyone remember the solar eclipse in August 1999?

No. It was not visible at all from the US. I will never forget the one in 2017, however. I drove to South Carolina and experienced totality, which was amazing.

I do. I was at work at a big company and everyone left the office to watch.

yes

I drove a full day to find a spot to watch it and it was totally worth it

Yes. Not mysterious, but, awesome.

I don’t remember

Well, I'm not you so I can't say whether it was as significant and mysterious as it felt to you at the time.
