Ah the memories!
I was born and raised in Gravesend (that's why I'm using a pseudonym), just up the A2. Fortunately I managed to escape when I was 17...
During the mods and rockers days it was always us against the Medway towns. Chatham in particular - it had the dockyard - so baiting hairy-arsed matelots was always a good game.
As you say Snodland isn't strictly Medway but close enough and with a name like that it deserved a good kicking.
And of course there's Thong. There used to be a secluded part down there called Lovers Lane where cars and their occupants collected. We called it 'bogging', an early form of - you guessed it - dogging, where miscreants and n'erdowells like us lads would creep up to see what they were doing. Oh how we laughed.
Medway <tch> Mind Those prize pillocks in Gravesend council renaming the district as 'Gravesham' takes some fucking beating.
/Tombstone - cos that's literally what it is. (Sorry, slightly off-topic - got carried away)
