I spent a lot of time in the piti bomb holes and hap's reef. Bomb holes were great night dives on full moon nights. I took a wreck diving course while there, so have done most of the wrecks around Guam. Blue hole was cool. Never got what all the interest in Crevice was, other than a good dive for deep dive training. I did some dives on Saipan, Palau and Truk while over there. I am intending to go back with some dive buddies probably around the end of 2014 and spend a couple of weeks on Guam, visiting friends and trying to get in some diving on most every day of the trip. Good bang for the buck. There are a lot more dive locations charted now than when I was out there.
