I think everyone remembers their first world cup - a good way of finding out what generation someone is - and that and Mexico 86 are the ones that I have the fondest memories of.
Italia 90 still lives long in my memory
the quality of football was generally pretty poor but the comedy/drama quotient was very high esp the final which was one of the dirtiest ever!
I'll never forget going out on the streets of Boston after the final.USA '94 I have a better recolection of... baggio's penalty miss!!
