not the biggest but the most memorable for me as a young lad was Mansfield away in the old 3rd div,
i lived in Mansfield at the time, and all i can remember is every side of the ground full with Villa fans, it was a night match as well, the noise and atmosphere was incredible,
i think it was an important game to clinch promotion, which we didnt do that night as i think the it was a drawn game.
this also was my first ever Villa game, i'm sure every away day in div 3 was the same back then, but it was the one i remember most, when the chant of 'Villa Villa' went round the ground it was unbelievable
Also Anderlecht away caught every one by supprise,
especially there police force who couldnt cope, dont know how many they were expecting but eveyone was spilling out into all areas of the ground,
i was in a side stand in what i imagine was the official away section, but it was pretty packed behind the goal as well and no end of mither which carried on throuout the whole match
