I recall scuba(ing) with the GF (now wife) around black rock. Also drove around the island in a rental caddy.
The party people use to jump off black rock into the water near their boat (for pick up).
Aloha
Yep, folks still do jump off black rock, you can now add me to that list now too, I did it yesterday!
The biggest pain is getting up to the jumping point without shoes though, ouch!
But well worth it, it seems much higher when you're up there than it looks from down below...
Well, I'm off to go hit the breakfast buffet and get ready for another lazy day on the beach and around the pool, good times...
