41 used to go with my dad from age of six or seven, then standing in kippax with about 20 mates which has sadly dwindled to two or three of us since all seating, though most of the lads still go just scattered about the ground. I miss the standing days and must admit that I'll always go but my enjoyment isn't even half of what it was when we went on the piss Saturday afternoons and dived into the kippax a minute before kick off into a swaying mass of people. So 35 years all told.
