I don't know if it would have made a difference in Colin's station and we never really thought about it before he left for boot camp... He is on a 270. He wants to be an OS. On his dream sheet, this was when you could put down specific units not just districts, he put 110's and 87's. Had he thought of it, maybe in the notes section he could have included something like "Have a desire to go OS, would like a smaller boat now since that will not be an option after A School." Would it have mattered? I can't say. But if you want to use the notes section maybe something a little more creative as to the reasoning other than "Because I know where all the happening bars are in that area" might get you something you want!
It was just a thought we had, just a suggestion I'm throwing out there.
But remember, wherever you go, enjoy it!! Who knows if you will ever go back there again and you don't want to miss out on an amazing opportunity to explore a new area because you didn't get exactly what you may have wanted.
Also, nothing is more constant in the military than change. If you don't like your station, your shipmates, your command... someone will be transferring (you or them) and then you can move on to the next situation and it should get better!
