I spent some time with Rob at Christmas Island and did a few dives with him on Oahu a few years ago. He contacted me about a week ago to discuss doing these dives together. I told him that I no longer lived in Hawaii, and that I thought it was a bit risky. We also made plans to work together in the near future.
So sorry to hear this, Rob was a great guy and my condolences go out to his wife and daughter.
Sincerely,
Brian D. Greene
