Watch out for Walts in the pubs in Dartmouth trying to impress each new intake. Walts are everywhere, pretending to be 'Navy'. Oh, don't take your iPod onto the parade ground- as young 'Batch' would. Any one of the hairy arssed parade staff will tear you a new one.
Be sure to keep posting when you get there and tell us all about it.
In the old days the pubs in Dartmouth were also 'owned' by various groups, like the rugby crowd monopolised the Floaters and so on, so it was sensible to be selective about where one drank.
In general keep focused on where you want to be, life will be hard and very different but it is just something to get through on your way to where you want to go, learn adapt and keep commited it is all worth it.
