Well, I spent some time on DG way back in the 80's or early 90's. The carrier pulled in there like 5 times one deployment. (I was in a squadron onboard at the time.) Nice beaches, nice view, lots of crabs and supposedly sharks in the water. The one club I went to was OK, first time I drank red beer. And a couple of the folks from the VP squadron deployed there took us in and fed us amareto sours one night too. I think the VPers were about the only females on the island back then.
Anyway, good luck and all of that. Spending that much time away from the family surely sucks. But hopefully in the end it will work out for the best. Is this a job that will help you towards making Chief?
