I am reminded of a site I used to visit before I moved to Hawaii. That site is http://www.mjq.net/fiveo/ and has a wealth of info on the original Hawaii-50 series.
Of interest was the link to the analaysis of the main title shots, such as where items were filmed, etc.
Especially fun at work, I played this link for the Hawaii lovers. It is the worst version of the Hawaii-50 theme, yet it grows on you. http://www.mjq.net/fiveo/opus501.wav
You can spend hours browsing the site and now I see they added the new series links.
I hope this gives you something to do now
