I love Kenilworth Road once I'm at the ground, but I hate the lack of friendly pubs, Luton being on the wrong railway line, often being kettled / marched back to the station. It doesn't add up to a good away day for me.
My all time worst away day was Leeds United. Miles from the station, horrible walk through wasteland and along dual carriageways, no pubs on the way, police that couldn't be arsed to deal with Leeds fans being twats in the pub opposite the ground, away fans stuck up in a corner, lost 3-0. I'm unsure whether I should go again to try to get a new perspective on the place or just sack it off. They've capped away tickets at £30 so I'll probably go.
