I was over there in April, the inlaws from japan also met up with us out there. We went to diamond head (nice views), north shore (bonzai pipeline), a bunch of malls, went to several beaches, a bunch of restaurants,
the yard house (had a monday night football atmosphere), looked at homes, hiking tour in the mountains to see a nice waterfall, passed by Obama's childhood home. Rainbows everyday....oh and did I mention the hottest Hawaiian local girls and a lot of Japanese girls.
The only thing I did not like was the ocean water is not as warm as Mexico or Peurto Rico, it was kind of cold.
