At least one here :-) I've been to Herrang a few times as well, but unfortunately after Frankie Manning's retirement. I got to listen to Dawn Hampton though which was great. It's pretty popular with tech people (at least in Australian and UK circles) so I'm sure there are more of us on HN.

(Herrang is a small village (pop 400) in Sweden which becomes an international swing dancing festival / camp for 5 weeks each summer)

Frankie Manning has a good autobiography published - https://frankiemanning.com/book.php well worth reading for an idea of what his days looked like. He was at some historic events like battle of the bands with Count Basie and Duke Ellington.

Re. missing the dancing: I know it's not the same as the real thing, but have you tried joining some "local" zoom classes? I found it really fun to drop in to a random one across the world.
