I enjoyed your TR. My son just moved to Oahu with the military so I'm in the beginning stages of making plans for our visit(s)!!! I've been to Oahu once, but never the other islands! I definitely want to incorporate at least a one night stay at Aulani!
I'm a scuba diver and we wear a knife mostly for fishing line that can cause problems. Absolutely no need for one when snorkeling--it was (hopefully) all for show. Some people like to try and kill things to feed to the fish. Hopefully he wasn't doing that.
I had to laugh. When I first read you went to the ABC store I thought, "alcohol" because in Virginia the ABC stores are the state run stores that sell liquor (other stores can only sell beer and wine). After your continued comments I realized it wasn't a liquor store!
