Sorry HIKEtube, but this list is kinda funny. Waaaaaaay too generic a list and very hard to take it serious. For instance, although the bear spray may be an important item to bring in certain areas, Hawaii is not one of them. Leave the bear spray at home and instead bring mask, fins, and snorkel maybe. Or replace it with money for shave ice wink . So one suggestion is to be more area or region specific. Bungee cordes? I suppose......but a camping essential? I suppose you could use it to strap your boom box to the backpack. As previously mentioned, it sounds like you carrying a lot of unnecessary weight but you are not bringing a camera to record the adventure?
