All four football leagues and below?
For some reason, I woke up this morning trying to think which clubs had played in all four leagues AND in the National League and below in their history. I was excluding clubs that had started outside the Football League and then played in the four divisions (Wimbledon, Northampton and Wigan come to mind in that category); it was clubs that had played in all five leagues AFTER joining the Football League
I could only come up with five clubs that fit my definition:
Luton Town
Notts County
Leyton Orient
Carlisle
Bradford Park Avenue
Can anybody think of any others?
