FEBRUARY 19, 2010 is truly a red letter day in the history of Manchester United, because it marks 100 years since Old Trafford was opened. It only made one paragraph on the front page of the Manchester Guardian, but it has become the iconic home, the Theatre of Dreams, for the Reds. To celebrate the Manchester Evening News is producing a 48-page special called Dream Factory celebrating a century of glory. The reporters and historians have been briefed but now it's your turn. We'd like to know what your favourite memories of going to the ground are. What was your favourite game? What is the funniest thing that has happened to you at OT? Have any milestones in your life occurred at the stadium? Or tell us about your first ever visit. You can also send pictures in via e-mail to email@example.com but please make sure the files are no bigger than one megabyte in size. You can send your memories via the comment box below or to firstname.lastname@example.org . They will not be published below however, but saved and considered for publication in the supplement. The deadline is mid-January so don't delay in getting the info to us, and make your own piece of United history.
