Elland Road as your first away? That's bold Albert! I suppose it wasn't as intense back then.
First away was at Blackburn in the 1964-65 season. My granddad took me and a mate from school. We won 5-0 with a hat-trick from Bobby. John Connelly and David Herd got one apiece. I didn't start going to away games without an adult until the 1966-67 season, and then it was restricted to supporters' club coaches to places like Burnley or Stoke.
