Gillingham away in 1987. Got bricked and bottled as we left the ground, then we had the Police at Victoria station waiting with dogs - I was towards the front and as everyone pushed forward the nice snarling, growling police dog got closer and closer! The highlight was one of the Pikeys throwing bricks at us got run over - oh how we laughed!
I just checked the order of games that season. That was my second ever away game (first was Southend). Missed the bricks (and therefore the running over) but not a fair amount of handbags down to the station and certainly had fun with the doggies at Victoria. Later the same season I came within about a foot of being trampled by a charging Police Horse away at Brentford. Still went to about double the number of aways the next season.
Leaving the Old Den for the first time was pretty scary, definitely a mouth closed, head down experience. Got followed in Stockport before a game but luckily never after.
