Looks like E mail is not going to work. Looked up photo under Key West, and did not recognize Dave. I was OT2 then and lived off base with two others in watch section in Barrigada. I have a friend who lives in Oregon who might remember him since we were both at Guam and Coos Head. He must have really enjoy scuba diving to make Guam his first choice. Like you, I would have picked Pt. Sur or Coos Head, but Guam was not as bad as Midway Island. By the way, did you know Mike Ferry? That name rings a bell from the Key West photos.
Both Mike Ferry and Tom Patterson were in the same OT class that I was and we often went snorkeling together. Being from Iowa I thought it was really neat, especially all the tropical marine fish! The day we were snorkeling off Boca Chica Key (photo) some guy walked past Dave's car and stole his billfold out of it, jumped in a car down the road, and took off. We gave chase and recovered the billfold but his money was gone.
Key West was not a friendly place to sailors. There was an unofficial "Dungaree Liberty" called while I was there after a couple of sailors were jumped on Duvall Street. Shortly after arriving on Key West, Hurricane Camille past 90 miles to the south of us. Plan was to put us in underground bunkers if the storm came closer. I guess you remember what happened to the streets when we just had a rain shower. Probably not a good plan.
My old desktop computer is still running under Windows XP and the email link failed using both Firefox and IE to look at messages. My laptop under Windows 10 seems to be able to deal with the link if I install Mail or Outlook. Guess it is just an XP thing that doesn't open the link anymore.
An email link does not usually (to my knowledge) open in a browser. It instead opens the default mail program on the computer you are on so if you do not have a mail program (outlook, thunderbird, live mail, etc) installed then it will not open the link. However if you mouse over the link you should be able to see the email address down in your status bar so you can use it somewhere eles (webmail, etc.)
