Had some good runs in Chatham - had my first pint in the High St, at a pub that is now a gambling machine hall at the tender age of 16 (as a Pt3 trainee in Pembroke).
Returned three further times, to see the old town die off slowly, more so when they closed the dockyard.
Some of the watering holes are still there, but not the same atmosphere.
Pembroke is part of a Uni campus, the parade ground, drill hall, swim baths and some of the accom blocks are still standing, and there is a brand new copshop built near where Gillingham gate to the yard is.
