Haha, by all means, I'll keep an eye out. Biggest thing to remember, the whole state is amazing and beautiful and "Paradise", blah, blah, blah, but You kinda have to treat ALL of O'ahu like a major City, replete with all of the problems of a major City, including gangs and crack and strong arm robberies, carjackings, killings, etc., etc., etc. That said, as long as You are aware of Your surroundings, things will be fine. Explore the other islands, if given the chance. In particular Kaua'i and the Big Island, as the coolest places in Hawai'i are on those two islands, IMO.
You said You'll be living in Haleiwa, right? That counts as the North Shore, FYI. Some would argue the coolest part of it. Oh, and wait 'til "Winter", those nice flat lake-like beaches will unleash the beast!
::edit:: I read wrong, You'll be living near the NS, so I'm guessing Scholfield? Not too far, at all. Then again, nothing in Hawai'i is, even if it still takes a long time to get where You're going, lol.
